PleaseeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeSimplify -2^3

mars1129 [50]

Answer:

Therefore,

$(-2)^{3}=-8$

Step-by-step 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

$a^{3}=a\times a\times a$

so for negative a i.e -a

$(-a)^{3}=-a\times -a\times -a$

substituting a = 2 we get

$(-2)^{3}=-2\times -2\times -2$

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

Therefore,

$(-2)^{3}=-8$
