-Explain how to solve for an unknown exponent (x) with an example. -Explain with an example how to simply an algebraic expression containing rational exponents.

Solving for a missing exponent can be as simple as solving 4=2^x, or as complex as finding how much time must pass before an investment is doubled in value. (Note that the caret refers to exponentiation.) In the first example, the strategy is to rewrite the equation so both sides have the same base.
