Question

X3-y2 if x = 2 and y = 3/4

Answer 1

it would be 6-1.5 so the answer would be 4.5 or 4 1/2 or 4 2/4

Answer 2

119/16

I'm assuming you meant x^3 - y^2 and solving this question :)

Substitute the given values for x and y in the expression and solve:

2^3 - (3/4)^2 = 8 - 9/16 = 128/16 - 9/16 = 119/16

hope this helps! <3
