Answer:
5
Step-by-step explanation:
If p is -1 and q is 4 then the square root of q is 2 and 2 * -1 = -2
-2+1=-1
-1^2=1
Now you can solve it from left to right so 2^3 is 8 and 8+1-4=5
2^3 + (p[tex]\sqrt{q}[/tex] + 1)^2 - 4
fill in p = -1 and q = 4
2^3 + (-1[tex]\sqrt{4}[/tex] + 1)^2 - 4
simplify
8 + (-1(2) + 1)^2 - 4
8 + (-2 + 1)^2 - 4
8 + (-1)^2 - 4
8 + 1 - 4
