Exponents RulesThe following table gives the Rules of Exponents.
There are different rules to follow when multiplying exponents and when dividing exponents. If we are multiplying similar bases, we simply add the exponents. If we are dividing, we simply subtract the exponents. If an exponent is outside the parentheses, it is distributed to the inside terms. It's important to understand the rules of multiplying exponents so that we can simplify expressions with exponents. ExamplesSome complex expressions can be simplified by using the above rules. Take the following example
Swap the negative exponents from numerator to denominator and viceversa.
Add the exponents of the products with the same base:
Take the next example:
Swap the terms to make the exponents positive:
Subtract the exponents of the similar bases:
