Answer to Problem 10:

Low estimate:  3;   high estimate:  5.   Since  By using these values, I determined my low estimate by knowing that 3 is close to, but less than.  I determined my high estimate by realizing that 5 is close to but more than.  By using the 3^rd and 4^th roots one can use known values to estimate an unknown quantity.
