Answer:

d. m = 9/4

Explanation:

You want the solution to ...

1/√8 = 4^(m -3)

Powers of 2

It will be convenient to rewrite this equation in terms of powers of 2.


(1)/(√(8))=4^((m-3))\qquad\text{given}\\\\\frac{1}{2^{(3)/(2)}}=(2^2)^((m-3))\qquad\text{using powers of 2}\\\\-(3)/(2)=2(m-3)\qquad\text{equate the exponents of 2}\\\\-(3)/(4)=m-3\qquad\text{divide by 2}\\\\\boxed{m=(9)/(4)}\qquad\text{add 3}
