Answer 2

$\huge\sf\orange{{\underline{answer}}:}$

$\bf{To~find:}$

$\sf{The~value~of~following,~using~suitable~identities}$

$\bf{~~~~~~a)~~67×73}$

$\sf{:→ (70-3)(70+3)}$

$\sf{Identity:~(a+b)(a-b)=a^{2}-b^{2}}$

$\sf{:→ 70^{2}-3^{2}}$

$\sf{:→ 4900-9}$

$\sf{:→ {\underline{\underline{4891}}}}$

$\sf{ }$

$\bf{~~~~~~b)~~98^{2}-2^{2}}$

$\sf{Identity:~a^{2}-b^{2}=(a+b)(a-b)}$

$\sf{:→ (98+2)(98-2)}$

$\sf{:→ 100×96}$

$\sf{:→ {\underline{\underline{9600}}}}$
