      6. We use the definition of the quantity log b a as being the number which you must raise b to in order to get a (when a>0).In other words, blogb a = a by definition. So, log 5 125 = 3 since 5 3 = 125,log 4 1 2 = −1 2 since 4−1/2 = 1 2, log1000000 = 6 since 106 = 1000000, log b 1 = 0 since b0 =1,ln(ex)=x since ex = ex (ln(a) means log base-e of a, where e ≈ 2.718). 7.
