With a calculator, you can simply calculate:
x = log 2 36 = log 36 / log 2
Without a calculator, you know that x must be a little over 5, since 2 5 = 32. Now:
2 x = 2 x 5 2 5 = 36 2 x 5 = 36 / 32 = 1 + 1 / 8
Using the fact that for small log b ( 1 + x ) x / ln b
( x 5 ) = log 2 ( 1 + 1 / 8 ) 1 8 ln 2
x 5 + 1 8 ln 2 5 + 1 5.6
