How do you find the value of a logarithm using the change of base formula?

The problem is log base 2 of 8.|||If you can, use exponential form instead. If log2 of 8 = x, then 2 ^ x = 8 so x = 3. But using change of base,





log2 8 = log10 8 / log10 2 so use a normal calculator to get the answer since its l;og button is log base 10
