Question

If x=5 and y=2 ...........................

Answer 1

${ \bold{ - 5}}$

${ \red{ \tt{given \: {\to}}}} \: { \bold{x = 5}} \: \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: { \bold{y = 2}}$

${ \green{ \tt{ \sqrt{10y + x} - xy}}}$

${ \green{ \tt{ \sqrt{10(2) + 5 } - 5(2)}}}$

${ \green{ \tt{ \sqrt{20 + 5} - 10}}}$

${ \green{ \tt{ \sqrt{25} - 10}}}$

${ \green{ \tt{5} - 10}}$

$= { \bold{ - 5}}$
