I was just wondering if someone can check my work on this problem.
I attempted to put the resulting x value back into the following equation as a checkCode:
(1/4)^x=75 //original equation
x log (1/4) = log 75 //take log of each side
x= log 75 / log (1/4) //divide by log (1/4)
x = -3.1144 //solve
and got the following answer on my check 2.14e-10
