Answer 1

Answer:

-1 bcoz

-1×(-1)=1×(-1)=-1

Answer 2

Answer:

Hence the cube of -1 is -1

Step-by-step explanation:

According to the information given in the above question,

The given value is -1

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 -1

Cubing the above term we get,

$=-1^{3} \\=-1\times -1\times -1$

Multiply -1 into -1 we get 1,

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

$=1\times -1$

Multiply 1 into -1 we get, -1

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

$=-1$

Hence the cube of -1 is -1
