The properties of exponents allow expressions with exponents to be rewritten.
When powers with the same base are multiplied, they can be written as one power by adding the exponents.For example, can be expressed as follows using this rule. This rule can be explained by writing the powers as repeated multiplication.
This rule is valid for all values of and when For the rule to be true, when it is necessary that and that Note that the rule might lead to non-real solutions when and at least one of the exponents is not an integer.
Simplify the following expression using the properties of exponents.
