Question

What is the value of -2 to the power of 4

Answer 1

-16!!

-2x-2x-2x-2= -16.

Answer 2

We can find the value if we write the complete expression:

`(-2)^4=(-2)\cdot(-2)\cdot(-2)\cdot(-2)`

Considering only two factors at a time, and knowing that - * - = +, we have:

`(-2)\cdot(-2)\cdot(-2)\cdot(-2)=4\cdot4=16`

Therefore, (-2)^4 = 16
