Select the equivalent expression

Given:

The given expression is

We need to determine the equivalent expression.

Equivalent expression:

The equivalent expression can be determined by solving the given expression.

Let us apply the exponent rule,

Thus, we get;

Again, applying the exponent rule,

Thus, we have;

Simplifying, we get;

Thus, the equivalent expression is

Hence, Option C is the correct answer.

linear pair postulates

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
