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
