Evaluate the expression if a = 3 over 4, b = -8, c = -2, and d = 3

45

Step-by-step explanation:

So we have the expression:

And we want to evaluate it for a=3/4, =-8, and d=3.

Thus, substitute in these values:

Do the exponent first. -8 squared is positive 64:

And 3/4 times 64 is 48:

Subtract:
