Answer 2

Answer:

Hence the cube of -2 is -8

Step-by-step explanation:

According to the information given in the above question,

The given value is -2

We have to find the cube of given value,

As we know that cube of a number is to multiply the number by itself by 3 times,

Given -2

Cubing the above term we get,

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

Multiply -2 into -2 we get 4,

When product to two -ve sign output is +ve, that is (- x -)=(+)

$=4\times -2$

Multiply 4 into -2 we get, -8

When product to two sign +ve and -ve output is -ve, that is (- x +)= (-)

$=-8$

Hence the cube of -2 is -8
