If you don't know what this means, let me show you. The only thing this is asking is to what power do we raise 2 to equal 8? Now 8 is the third power of 2. So log base 2 of 8 equals 3. But what if we had log base 2 of 1 over 8? Well, the same exponent rules we all know still apply. We have a negative power and we take the reciprocal of that.

So log base 2 of 1 8 is just -3 because 2 to the3 is 1 over
