Question

Which expression is equivalent to

A: -4^8
B: -8^4
C: (- 8) ^4
(-4) ^ 8

Answer 1

A: -4^8

Explanation:

-A negative number times a positive number results to a negative number.

-The first term of the expression is a negative while the last 4 parts are negative.

-The last 7 terms results to:

`x^n=x^n\\\\=4^7`

We multiply by the first term:

`(-4)^1* 4^7\\\\=-4^8`

Hence, A is the correct option
`-4^8`
