Question

Xy2(x-5y) + 1 for x =2, y= 1

Answer 1

$If \: x = 2 \:and \:y = 1 \: then$

$\red{ Value \: of \: xy^{2}(x-5y) }\\= 2\times 1^{2} ( 2 - 5 \times 1 ) \\= 2( 2-5) \\= 2 \times (-3) \\= -6$

Therefore.,

$\red{ Value \: of \: xy^{2}(x-5y)} \green { = -6 }$

Answer 2

x = 2

x = 2y = 1

$x \times {y}^{2} (x - 5y) + 1$

$\: = 2 \times {1}^{2} (2 - 5)$

$= 2 \times - 3$

$= - 6$
