To solve the exercise we use the power property:
We use the property with our exercise and solve:
We use the formula:
Therefore, we obtain:
Let's keep in mind that the numerator and denominator of the fraction have terms with the same base, therefore we use the property of powers to divide between terms with the same base:
We apply it in the problem:
Remember that any number raised to the 1st power is equal to the number itself, meaning that:
Therefore, in the problem we obtain:
Therefore, the correct answer is option a.
Note that in the fraction and its denominator, there are terms with the same base, so we will use the law of exponents for division between terms with the same base:
Let's apply it to the problem:
Therefore, the correct answer is b.
\( (4^2)^3+(g^3)^4= \)
\( (y\times x\times3)^5= \)

\( \frac{81}{3^2}= \)
We use the formula:
We use the formula:
We use the formula
Therefore, we obtain:
We use the formula:
Therefore, we obtain:
First, we recognize that 81 is a power of the number 3, which means that:
We replace in the problem:
Keep in mind that the numerator and denominator of the fraction have terms with the same base, therefore we use the property of powers to divide between terms with the same base:
We apply it in the problem:
Therefore, the correct answer is option b.

We can therefore deduce that the correct answer is option B.
We begin by using the power rule of negative exponents.
We then apply it to the problem:
We can therefore deduce that the correct answer is option A.
We begin by using the power property for a negative exponent:
We apply it to the problem:
We then subsequently notice that each whole number inside the parentheses is raised to a negative power (that is, the number and its negative coefficient together) When using the previously mentioned power property: We are careful to take this into account,
We then continue by simplifying the expression in the denominator of the fraction, remembering the exponentiation property for the power of terms in multiplication:
We apply the resulting expression
In summary we are able to deduce that the solution to the problem is as follows:
Therefore, the correct answer is option B.
Using the rules of negative exponents: how to raise a number to a negative exponent:

To begin with we deal with the expression in the denominator of the fraction. Making note of the power rule for exponents (raising an exponent to another exponent):
We obtain the following:
We then return to the initial problem and apply the above information:
In the last step we remember that:
Next, we remember the Negative Exponent rule ( raising exponents to a negative power)
We apply it to the expression we obtained in the last step:
