Question

What is the value of this expression when x = -5 and y = -3
`(2)/(3) x^(3) y^(2)`

Answer 1

y = - 750

Explanation:

Given

y =
`(2)/(3)` x³y² ← substitute x = - 5, y = - 3 into the expression

=
`(2)/(3)` × (- 5)³ × (- 3)²

=
`(2)/(3)` × - 125 × 9 ( cancel the 3 and 9 )

= 2 × - 125 × 3

= - 750
