Sam decided to lose weight and went on a diet. The figure below depicts a graph, showing how his weight changed during the year. Using this graph, answer the following questions: e
During which time of the year was Sam losing weight the fastest?

11 - 12 months

^

Step-by-step explanation:

It shows on the graph that the lowest slope is at 11 - 12 months.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
