11-4

I wasn't at school for this section (or 11-3) so i decided to do my blog on this section to see if I'm doing this right... I'm only using a similar example from the notes to help guide me through it

Find the fourth root of 16.
 (In the end i understand how to do "k" and all that but im not 100% sure how to find "n" though i think its found by the closest square root. For example, for 8, "n" would be 3 because 9 is the closest perfect square and the square root of 9 is 3 but yeah unsure.)

Hope you can read it. I honestly think it would be harder to understand if i would have typed it instead...
