Now we have log 36 with a base of 2.

We can only do logarithms with a base 10 or e on a calculator... so, we need to use the formula to change the base.

Change it to 10 and type

log (36) /log (2)

Remember the formula?

5 and 4 will move (5 in the numerator and 4 in the denominator), and you can choose a new base to be whatever you want.

e or 10 will work.
