Question

PleaseeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeSimplify -2^3

Answer 1

Therefore,

`(-2)^(3)=-8`

Explanation:

Simplify

-2^3

`(-2)^(3)`

It is read as negative 2 raised to the power three,

also it is the cube of negative 2

we know that
`a^(3)`given as

`a^(3)=a* a* a`

so for negative a i.e -a

`(-a)^(3)=-a* -a* -a`

substituting a = 2 we get

`(-2)^(3)=-2* -2* -2`

negative sign multiplied by odd number of times then the sign remains negative.

Therefore,

`(-2)^(3)=-8`
