Answer 2

Answer:

Hence the square of -9 is 81.

Step-by-step explanation:

According to the information given in the above question,

The given value is -9.

We have to find the square of given value,

As we know that squaring of a number is to multiply the number by itself,

Given -9,

Squaring the above term we get,

$=-9^{2} \\=(-9)\times (-9)$

Multiply -9 into -9 we get, 81

When we multiply two product of -ve sign we get +ve, as (- x -) output will be +ve, also squaring of -ve number but output will be in +ve,

$=81$

Hence the square of -9 is 81.
