Question

A very easy question..
Find the value of
$\large\underline{\bf{ \maltese \: \: {x}^{2} \times {x}^{2} - {y}^{2} - {y}^{2} }}$
when x=3
and, y=2​

Answer 1

Answer:

(3)² x (3)² - (2)² - (2)²

= 9 x 9 - 4 - 4

81 - (4+4)

81 - 8 = 73

1Step-by-step explanation:

Answer 2

$\rm \: {x}^{2} \times {x}^{2} - {y}^{2} - {y}^{2} \: \: \: when \: x = 3 \: \: and \: \: \: y = 2$

$\begin{array}{l} \rm(3) ^{2} \times (3) ^{2} - {(2)}^{2} - {(2)}^{2} \\ \\ \rm\implies9 \times 9 - 4 - 4 \\ \\ \rm\implies 81 - 4 - 4 \\ \\ \rm\implies 77 - 4 \\ \\ \color{aqua} \colorbox{red}{\rm ⟹ \: 73}\end{array}$
