Answer:
-20
Step-by-step explanation:
4p^2 + 7q^3
4(-3)^2 + 7(-2)^3
4(9)+7(-8)
36 - 56 = -20
For this case we have the following expression:
[tex]4p ^ 2 + 7q ^ 3[/tex]
We must find the value of the expression when:
[tex]p = -3\\q = -2[/tex]
Substituting we have:
[tex]4 (-3) ^ 2 + 7 (-2) ^ 3 =\\4 (9) +7 (-8) =\\36-56 =[/tex]
Different signs are subtracted and the sign of the major is placed:
[tex]36-56 = -20[/tex]
Answer:
The value of the expression is -20
