which of the following expressions is equivalent to (-7)^5

-7 x -7 x -7 x -7 x -7
-7 x 5
(-7) x 7 x 7 (-7) x 7 x -7
5x5x5x5x5x5x5

-7 x -7 x -7 x -7 x -7

To find the equivalent expression of (-7)^5, we need to simplify it step by step.

The expression (-7)^5 corresponds to raising -7 to the 5th power.

(-7)^5 is equivalent to (-7) x (-7) x (-7) x (-7) x (-7).

So, the first equivalent expression is -7 x -7 x -7 x -7 x -7.

This expression can also be rewritten as (-7) x 5 since multiplying a number by itself is equivalent to raising it to the power of 2 (e.g., (-7) x (-7) = (-7)^2).

However, (-7) x 5 is not equal to (-7)^5.

Therefore, the expression (-7) x 5 is not equivalent to (-7)^5.

The next expression, (-7) x 7 x 7 x (-7) x 7 x -7, is not equivalent to (-7)^5.

Lastly, the expression 5 x 5 x 5 x 5 x 5 x 5 x 5 is not equivalent to (-7)^5.

So, the correct answer is -7 x -7 x -7 x -7 x -7.
