(−2)5

Enter your answer in the box.

Answer 1

-10 since the parentheses mean multiply and multiplying a negative with a positive gives you a negative.

Answer 2

Answer: -32

Explanation:

Using law of exponents:-

`a^n=a* a* a .......a (\text{ n times})`

The given expression :
`(-2)^5`

Then , we need to multiply -2 to itself 5 times.

i.e.
`(-2)^5=-2*-2*-2*-2*-2=-32` (Product of odd numbers of -negative signs results in negative sign )

Therefore , the value of this expression = -32
