Question

What is -2 raised to the power of -3? I just need it explained.

Thanks! :)

Answer 1

-2^-3
1/-2^3

Answer 2

x^-3=1/x^3

Answer 3

Basically you are multiplying the number by itself by itself by the power. In this case '-3'
So...
It would basically be this:
\[-2^{-3}= -1(-2\times-2\times-2)\]
\[-1\times-8\]
\[=8\]

Answer 4

@Matty13579 are you sure in this ?

Answer 5

so -2^(-3) = 1/(-2)^3 = 1/(-8) = -1/8

because -2^3 = -2*-2*-2 = 4*-2 = -8 so will be

Answer 6

(-2)^-3 = (-2)^0-3 = (-2)^0 divided by (-2)^3
(-2)^0 = 1 and (-2)^3 = (-2)(-2)(-2) = -8
so it becomes 1/-8 = -1/8

Answer 7

I'm so confused now lol xD

Answer 8

when you divide numbers with the same base subtract the exponents

Answer 9

@jhonyy9
Yeah, I'm sure...

Answer 10

@Matty13579 sorry you made a mistake
-2^-3 is not -(-2)^-3
it would be -(+2)^-3
