Powers of fractions

The  exercise appears under the 6th grade (U.S.) Math Mission. This exercise practices the powers of fractions.

Types of Problems
There is one type of problem in this exercise:
 * 1) Evaluate the exponential expression: This problem has a numerical expression involving a rational exponent. The student is asked to find the value of the problem.

Strategies
Knowledge of the exponent rules, including negative and fraction values, is sufficient to perform the exercise accurately and efficiently.
 * 1) Negative exponents mean to reciprocate, and a fraction like $$\frac{1}{n}$$ means to find the nth root.
 * 2) The problems at this level tend to be a straight radical with no additional powers mixed in, although there is a possibility of needing to find the reciprocal of the answer.

Real-life Applications

 * 1) An ability to work well with exponents of all types is an advantage in calculus where derivatives can be made simpler via the "power rule."
