Question

4p squared + 7q cubed. p=-3
q= -2​

Answer 1

-20

Explanation:

4p^2 + 7q^3

4(-3)^2 + 7(-2)^3

4(9)+7(-8)

36 - 56 = -20

Answer 2

For this case we have the following expression:

`4p ^ 2 + 7q ^ 3`

We must find the value of the expression when:

`p = -3\\q = -2`

Substituting we have:

`4 (-3) ^ 2 + 7 (-2) ^ 3 =\\4 (9) +7 (-8) =\\36-56 =`

Different signs are subtracted and the sign of the major is placed:

`36-56 = -20`

Answer:

The value of the expression is -20
