Question

If x = 3and y = -5, find the value of (x-y)3

Answer 1

Answer:

x = 3and y = -5,

the value of (x-y)3

${(x - y)}^{3} = {(3 - ( - 5))}^{3} = {8}^{3} = 512$

Answer 2

$x = 3 \: \: \: , \: \: y = - 5$

$= (x - y) ^{3}$

$= [ (3) - ( - 5) ] ^{3}$

$= [ 3 + 5 ] ^{3}$

$= [ 8 ] ^{3}$

$= 512$
