Question

Find the value of the expression xy2–y3 for x=8.8 and y = −1.2

Answer 1

The value of the expression for these values is 14.4

Explanation:

We have the following expression

`xy^(2) - y^(3)`

We have to find the value when:

x = 8.8, y = -1.2

So we replace x and y by these values. So

`8.8*(-1.2)^(2) - (-1.2)^(3) = 14.4`

The value of the expression for these values is 14.4
