Question

please give me the answer of this question from algebraic expressions

Answer 1

$64 {x}^{2} + 81 {y}^{2} + 144xy$
where y=4/3 and x=11 =>
$\\ 64 {(11)}^{2} + 81 { (\frac{4}{3} )}^{2} + 144(11)( \frac{4}{3} )$
=>
$64(121) + 81 (\frac{16}{9} ) +48(11)(4)$
=>
$7744 + 9(16) + 48(44)$
=>
$7744 + 144 + 2112$
=>
$10000 \: is \: the \: answer \:$
