Question 105851: I'm guessing the answer is 4, but how do I solve this problem??
Solve the exponential function: 16%5Ex+=64

You can put this solution on YOUR website!
you could use logarithms, but then you'd need a table or calculator (or a slide rule?)

4%5E2=16 and 4%5E3=64 so %284%5E2%29%5Ex=4%5E3

using rules for exponents ... 2x=3


not a good guess...
