Answer 2

$\huge\bf\purple{Given:-}$

To find :-

1) a²-b²= ?

2) a²×b²= ?

3) a²÷b²=?

where a = 2 ,b = -1

$\huge\bf\red{Solution}$

$1. {a}^{2} - {b}^{2}$

$➠ {(2)}^{2} - ( - 1)$

$➠4 - 1$

$1)➠4$

$2)➠ {a}^{2} \times {b}^{2}$

$➠ {(2)}^{2} \times {( - 1)}^{2}$

$➠4 \times 1$

$2)➠4$

$3) {a}^{2} \div {b}^{2}$

$➠ {(2)}^{2} \div { (- 1)}^{2}$

$➠4 \div 1$

$3)➠4$
