Evaluating the necessary expression.
As is common knowledge, a number's square value is its value raised to the power of 2.
A negative number becomes positive when it is squared. because two negative integers usually add up to a positive number.
If we find square of a negative number, -x, here x>0, then,
-x×-x=x2
Here, x2>0.
So,
-72=-7×-7
-72=49
Therefore, the value of -72 is 49.
