To solve this problem, we'll follow these steps:

• Step 1: Confirm the given expression is $4^x \times 4^2 \times 4^a$.
• Step 2: Apply the exponent rule for multiplication of powers: if $b^m \times b^n = b^{m+n}$, use this with base 4.
• Step 3: Add the exponents of each term.

Let's work through these steps:

Step 1: The expression we have is $4^x \times 4^2 \times 4^a$.

Step 2: Since all parts of the product have the same base $4$, we can use the rule for multiplying powers: $4^x \times 4^2 \times 4^a = 4^{x+2+a}$.

Step 3: The simplified expression is obtained by adding the exponents: $x + 2 + a$.

Therefore, the expression $4^x \times 4^2 \times 4^a$ simplifies to $4^{x+2+a}$.

To reduce the expression $5^{2x} \times 5^x$, we will use the exponent multiplication rule:

When multiplying powers with the same base, add the exponents:
Thus, $5^{2x} \times 5^x = 5^{2x + x}$.

Hence, the correct choice is: $5^{2x + x}$.

In this case we have 2 different bases, so we will add what can be added, that is, the exponents of $3$

Step 2: We'll apply the property of exponents, which states that for the same base, you add the exponents: $b^m \times b^n = b^{m+n}$. In this case, it will be $2^{a+2}$.
Step 3: Rewriting the expression using this rule, we get: $2^a \times 2^2 = 2^{a+2}$.

Therefore, the solution to the problem is $2^{a+2}$.

To solve the expression $5^2 \times 5^a \times 5^3$, we will make use of the exponent rule for multiplication, which states that if you multiply powers with the same base, you add the exponents:

• Step 5: Express the final result as a single power:
  The expression can be rewritten using the exponent rule as $5^{5+a}$.

Thus, the final simplified expression is $5^{5+a}$.

Now, let's work through each step:
Step 1: The expression given is $3^{2a + x + a}$. Here the exponent is $2a + x + a$.
Step 2: We apply the rule $b^{m+n} = b^m \times b^n$ by rewriting the exponent sum as individual terms: $(2a)$, $x$, and $a$.
Thus, we can rewrite the expression using the property of exponents: $3^{2a + x + a} = 3^{2a} \times 3^x \times 3^a$.
Step 3: Upon expanding, the solution corresponds to option :

$3^{2a}\times3^x\times3^a$

Therefore, the expanded expression is $3^{2a}\times3^x\times3^a$.

To solve this problem, we will use the rule of exponents that allows us to expand the sum $a + b + c$ in the exponent:

• Given: $4^{a+b+c}$
• According to the exponent rule $x^{m+n+p} = x^m \times x^n \times x^p$, we can express:
• Step: Break down $4^{a+b+c}$ to:
• $4^a \times 4^b \times 4^c$

Therefore, the expanded form of the equation is $4^a \times 4^b \times 4^c$.

To solve this problem, we will use the properties of exponents:

• Step 1: Recognize that the exponent $10a + 5x$ can be expressed as the sum of two terms, namely $(5a + 5x) + 5a$.
• Step 2: Apply the property $g^{m+n} = g^{m} \times g^{n}$ to the expression $g^{10a + 5x}$.
• Step 3: Expand the expression using the identified split:
  Since $10a + 5x = (5a + 5x) + 5a$, we have:
  $g^{10a + 5x} = g^{(5a + 5x) + 5a} = g^{5a + 5x} \times g^{5a}$.

Thus, the expanded form of the expression is given by $g^{5a+5x} \times g^{5a}$.

To solve the problem, we can follow these steps:

• Step 1: Recognize that the given expression is $2^{2a+a}$.
• Step 2: Use the Power of a Power Rule for exponents, which allows us to write $a^{m+n} = a^m \times a^n$.
• Step 3: Rewrite the expression as follows:

Given: $2^{2a+a}$

Step 4: Simplify the exponent by splitting it:

Since the expression in the exponent is $2a+a$, we can write:

$2^{2a+a} = 2^{2a} \times 2^a$

Thus, applying the properties of exponents correctly leads us to the expanded form.

Therefore, the expanded equation is $2^{2a} \times 2^a$.

To tackle this problem, we need to expand the expression $7^{2x+7}$ using the properties of exponents:

• Step 1: Identify the structure of the exponent in the form $2x + 7$.
• Step 2: Recognize this as a sum of two components: $2x$ and $7$.
• Step 3: Apply the exponent rule $a^{m+n} = a^m \times a^n$ to separate the expression into two distinct exponent terms.

Now, let's proceed with the solution:

Step 1: Given the exponent is $2x + 7$, break it down into individual components:
$2x + 7 = x + x + 7$.

Step 2: Applying the rule $a^{m+n} = a^m \times a^n$:
$7^{2x+7} = 7^{x+x+7} = 7^x \times 7^{x+7}$.

Therefore, the expanded form of the expression is $7^x \times 7^{x+7}$.

We use the power property to multiply terms with identical bases:

$a^m\cdot a^n=a^{m+n}$
We apply the property for this problem:

$4^{2y}\cdot4^{-5}\cdot4^{-y}\cdot4^6= 4^{2y+(-5)+(-y)+6}=4^{2y-5-y+6}$
We simplify the expression we got in the last step:

$4^{2y-5-y+6} =4^{y+1}$
When we add similar terms in the exponent.

Therefore, the correct answer is option c.

We use the power property to multiply terms with identical bases:

$a^m\cdot a^n=a^{m+n}$We apply the property to our expression:

$7^{2x+1}\cdot7^{-1}\cdot7^x=7^{2x+1+(-1)+x}=7^{2x+1-1+x}$We simplify the expression we got in the last step:

$7^{2x+1-1+x}=7^{3x}$When we add similar terms in the exponent.

Therefore, the correct answer is option d.

We'll use the law of exponents for multiplying terms with identical bases:

$a^m\cdot a^n=a^{m+n}$
Note that this law applies to any number of terms being multiplied, not just two terms. For example, when multiplying three terms with the same base, we get:

$a^m\cdot a^n\cdot a^k=a^{m+n}\cdot a^k=a^{m+n+k}$
When we used the above law of exponents twice, we can also perform the same calculation for four terms in multiplication and so on...

Let's return to the problem:

Notice that all terms in the multiplication have the same base, so we'll use the above law:

$2^{2x+1}\cdot2^5\cdot2^{3x}=2^{2x+1+5+3x}=2^{5x+6}$

$$Therefore, the correct answer is a.

To reduce the given equation $a^{-3x} \times a^b \times a^b$, we will use the multiplication of powers rule for exponents, which states that if you multiply powers with the same base, you add the exponents.

Let's follow the steps:

• Step 1: Identify that all terms share the same base, $a$.

• Step 2: Apply the rule: $a^{-3x} \times a^b \times a^b = a^{-3x + b + b}$.

• Step 3: Simplify the exponents by adding them: $-3x + b + b = -3x + 2b$.

Therefore, the reduced form of the equation is $a^{-3x + 2b}$.
