Answer 2

$(93)^{2} \\= ( 100 - 7 )^{2}$

"_____________

By Algebraic Identity :

$\boxed { \pink { (a-b)^{2} = a^{2} + b^{2} - 2ab }}$

_______________"

$Here, a = 100, \: b = 7$

$= 100^{2} + 7^{2} - 2 \times 100 \times 7 \\= 10000 + 49 - 1400 \\= 10049 - 1400 \\ = 8649$

Therefore.,

$\red { Value \:of \: 93^{2}} \green {= 8649}$
