Exercise #12

(2×8×7)2= (2\times8\times7)^2=

Video Solution

Step-by-Step Solution

We begin by using the power rule for parentheses:

(zt)n=zntn (z\cdot t)^n=z^n\cdot t^n

That is, the power applied to a product inside parentheses, is applied to each of the terms within, when the parentheses are opened.

We then apply the above rule to the problem:

(287)2=228272 (2\cdot8\cdot7)^2=2^2\cdot8^2\cdot7^2

Therefore, the correct answer is option d.

Note:

From the formula of the power property inside parentheses mentioned above, it might seem as though it refers to only two terms of the product inside of the parentheses, but in reality, it is also valid for the power over a multiplication of many terms inside parentheses, as was seen above.

A good exercise is to demonstrate that if the previous property is valid for a power over a product of two terms inside parentheses (as formulated above), then it is also valid for a power over several terms of the product inside parentheses (for example - three terms, etc.).

Answer

228272 2^2\cdot8^2\cdot7^2

(2×6×8)4= \left(2\times6\times8\right)^4=

Video Solution

Step-by-Step Solution

To solve the question, we need to apply the power of a product rule from exponents. This rule states that when a product is raised to an exponent, we can apply the exponent to each factor within the product individually. Mathematically, the rule is expressed as:

(abc)n=anbncn (a \cdot b \cdot c)^n = a^n \cdot b^n \cdot c^n .

Now, we identify the components in the given expression:

  • The expression inside the parentheses is 2×6×8 2 \times 6 \times 8 .
  • The exponent applied to this product is 4 4 .

Applying the exponent to each factor gives us:

  • Apply the exponent 4 to the factor 2: 24 2^4 .
  • Apply the exponent 4 to the factor 6: 64 6^4 .
  • Apply the exponent 4 to the factor 8: 84 8^4 .

Therefore, the expression (2×6×8)4 (2 \times 6 \times 8)^4 is transformed into:

24×64×84 2^4 \times 6^4 \times 8^4 .

This matches the correct answer provided: 24×64×84 2^4 \times 6^4 \times 8^4 .

Step-by-Step Solution

To solve the expression 87×107 8^7 \times 10^7 , we can use the power of a product rule, which states that am×bm=(a×b)m a^m \times b^m = (a \times b)^m . Here,a=8 a = 8 and b=10 b = 10 , and both are raised to the same power m=7 m = 7 .

Following these steps:

  • Identify the base numbers and the common exponent: Here, the base numbers are 8 8 and 10 10 , and the common exponent is 7 7 .

  • This simplifies to (80)7 (80)^7 .

Thus, the rewritten expression is (8×10)7 \left(8 \times 10\right)^7 .

Video Solution

Step-by-Step Solution

We are given the expression: 23×43 2^3 \times 4^3 and need to express it as a single term using the power of a product rule.

The power of a product rule states that for any non-zero numbers a a and b b , and an integer n n , (a×b)n=an×bn (a \times b)^n = a^n \times b^n .

To apply the inverse formula, which is converting two separate powers into a product raised to a power, we look for terms that can be combined under a single exponent. Observe that:

  • Both terms 23 2^3 and 43 4^3 have the same exponent.

  • This allows us to combine them into a single expression: (2×4)3 (2 \times 4)^3 .

Therefore, according to the power of a product rule applied inversely, the expression 23×43 2^3 \times 4^3 can be rewritten as (2×4)3 (2 \times 4)^3 .

Video Solution

Step-by-Step Solution

To solve the expression (12×5×4)10 \left(12 \times 5 \times 4\right)^{10} , we apply the rule of exponents known as the "Power of a Product". This rule states that when you have a product inside a power, you can apply the exponent to each factor in the product separately. This can be expressed by the formula:

(a×b×c)n=an×bn×cn (a \times b \times c)^n = a^n \times b^n \times c^n

In the given expression, the base is the product 12×5×4 12 \times 5 \times 4 and the exponent is 10 10 .

Therefore, according to the power of a product rule, the expression can be rewritten by raising each individual base to the power of 10 10 :
