2. [tex]\huge\bf\purple{Given:-}[/tex]

   To find :-

   1) a²-b²= ?

   2) a²×b²= ?

   3) a²÷b²=?

   where a = 2 ,b = -1

   [tex]\huge\bf\red{Solution}[/tex]

   [tex]1. {a}^{2} – {b}^{2} [/tex]

   [tex]➠ {(2)}^{2} – ( – 1)[/tex]

   [tex]➠4 – 1[/tex]

   [tex]1)➠4[/tex]

   [tex]2)➠ {a}^{2} \times {b}^{2} [/tex]

   [tex]➠ {(2)}^{2} \times {( – 1)}^{2} [/tex]

   [tex]➠4 \times 1[/tex]

   [tex]2)➠4[/tex]

   [tex]3) {a}^{2} \div {b}^{2} [/tex]

   [tex]➠ {(2)}^{2} \div { (- 1)}^{2} [/tex]

   [tex]➠4 \div 1[/tex]

   [tex]3)➠4[/tex]
