Question

Which is the value of this expression when x=-2 and y=-3 10x^3y^2 -720 -360 360 720

Answer 1

-720 if the spaces are meant to be + signs

Answer 2

the value of the expression is -720

Explanation:

10x^3y^2

We need to find the value of the expression when x=-2 and y=-3

Plug in the value of x and y in the given expression

`10x^3y^2`

`10(-2)^3(-3)^2`

(-2)^3 = -2*-2*-2= -8

(-3)^2= -3*-3= 9

so
`10(-2)^3(-3)^2= 10(-8)(9)=-720`
