Answer:

Therefore,

[tex](-2)^{3}=-8[/tex]

Step-by-step explanation:

Simplify

-2^3

[tex](-2)^{3}[/tex]

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

also it is the cube of negative 2

we know that [tex]a^{3}[/tex]given as

[tex]a^{3}=a\times a\times a[/tex]

so for negative a i.e -a

[tex](-a)^{3}=-a\times -a\times -a[/tex]

substituting a = 2 we get

[tex](-2)^{3}=-2\times -2\times -2[/tex]

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

Therefore,

[tex](-2)^{3}=-8[/tex]
