Question

What is the value of the expression 5x^2y / 5x - y when x = 4 and y = 2?

a) 80 / 9
b)60 / 3
c) 16 / 5
d)8 / 1

Answer 1

This is similar to your 7:58pm post. In that case we interpreted x^2y as x^(2y) rather than (x^2)y. In that case y was 1, and the value was the same. In this case, I don't see any answers if x is raised to the 2y power. If it is interpreted as 5(x^2)y for the numerator and (5x-y) for the denominator one of the answers does match.
