Question
Find the values of the following: $(-7)^2$
✓
Answer
We know that If 'a' is natural number, then
$(-a)^{\text {even number }}=$ positive number
$(-a)^{\text {even number }}=$ negative number
We have,
$(-7)^2=(-7) \times(-7)$
$=49$
$(-a)^{\text {even number }}=$ positive number
$(-a)^{\text {even number }}=$ negative number
We have,
$(-7)^2=(-7) \times(-7)$
$=49$
