If x = 5 and y = -3, then x2 – y
3 =

Answer 1

Hi ,

put x = 5 , y = -3 in given expression

x² - y³

= 5² - ( -3 )³

= 25 - ( -27 )

= 25 + 27

= 52

I hope this helps you.

Answer 2

x = 5 and y = -3
Putting values of x and y in x² - y³
                         = (5)²-(-3)³
                         = 25 - (-27)
                         = 25 + 27
                         = 52.
Hence,  the solution is 52.
