Positive and negative exponents

The  exercise appears under the 8th Grade Math Mission. This exercise uses positive and negative exponents and strengthens the relationship between them.

Types of Problems
There are two types of problems in this exercise:


 * 1) Perform the negative exponent: This problem provides an exponential expression with a negative exponent. The student is asked to find the answer and write it in the space provided.Pane1.png
 * 2) Perform the positive exponent: This problem provides an exponential expression with a positive exponent. The student is asked to find the answer and write it in the space provided.Pane2.png

Strategies
The exponent rules are key to doing this problem efficiently and accurately.
 * 1) Negative exponents provide a reciprocation of the original problem.

Real-life applications

 * 1) The exponent rules are important because complicated concepts (like rational expression and radicals) can be represented in the world of exponents.
