Which expression is equivalent to the quantity five raised to the negative second power times three raised to the fifth power en
serg [7]

The equivalent expression is 5^(4) * 3^(-10)

<h3>How to determine the equivalent expression?</h3>

The statement is given as:

five raised to the negative second power times three raised to the fifth power end quantity all raised to the negative second power

Rewrite properly as:

(5^-2 * 3^5)^-2

Expand the expression by multiplying the exponents

So, we have:

5^(-2 -2) * 3^(5 *-2)

Evaluate the products

5^(4) * 3^(-10)

Hence, the equivalent expression is 5^(4) * 3^(-10)

In the second number, the 7 is moved 3 places to the right, and the 3 is moved 2 places to the right.


(The digit 4 is used here simply to make the numbers be the same overall length. It can be changed to any other digit (except 3 or 7) or removed. Digits that are not 3 or 7 can replace any of the zeros.)
