Answer:
45
Step-by-step explanation:
So we have the expression:
[tex]ab^2-d[/tex]
And we want to evaluate it for a=3/4, =-8, and d=3.
Thus, substitute in these values:
[tex]=(\frac{3}{4})(-8)^2-3[/tex]
Do the exponent first. -8 squared is positive 64:
[tex]=(\frac{3}{4})(64)-3[/tex]
And 3/4 times 64 is 48:
[tex]=(48)-3[/tex]
Subtract:
[tex]=45[/tex]
