Answer:
287
Step-by-step explanation:
-8h-2(5+f^3)+7g^2
Let f = -4, g = 5, and h = 3/4
-8 (3/4) -2(5+(-4)^3) +7 (5^2)
Using PEMDAS , parentheses first
(5+(-4)^3)
The exponents are first
5+-64 = -59
Replace this into the equation
-8 (3/4) -2(-59) +7 (5^2)
Exponents next
-8 (3/4) -2(-59) +7 (25)
Then multiply and divide from left to right
-6 +118+175
Then add and subtract from left to right
287
