evalute the following exactly
a) log%2812%2C1%29
b) log%282%2C16%29

log%2812%2C1%29 asks this question:

"To what power must the base 12 be raised in order to get 1?"

The answer to that question is:

"12 must be raised to the 0 power in order to get 1". 

Therefore log%2812%2C1%29=0

-------------------------

log%282%2C16%29 asks this question:

"To what power must the base 2 be raised in order to get 16?"

The answer to that question is:

"2 must be raised to the 4 power in order to get 16". 

Therefore log%282%2C16%29=4
