Learn how to simplify an exponent with a negative fraction as the power

The video tutorial explains how to handle powers in mathematical expressions, focusing on rewriting negative powers as positive. It demonstrates the process of moving negative powers from the denominator to the numerator and vice versa. The tutorial also covers the application of rules to simplify expressions, leading to the final answer. Assumptions about square roots and the notation used are clarified, ensuring a comprehensive understanding of the topic.

What is the main goal when dealing with powers in mathematical expressions?

• To make the powers negative

• To rewrite the powers as positive

• To eliminate the powers

• To add more powers

How do you convert a negative power in the denominator to a positive power?

• By moving it to the numerator

• By multiplying the power by -1

• By adding 1 to the power

• By subtracting 1 from the power

If you have X to the -1/2 power in the numerator, how would you rewrite it positively?

• X to the 1/2 power in the numerator

• X squared in the denominator

• X squared in the numerator

• X to the 1/2 power in the denominator

What is the result of rewriting X to the 1/2 power?

• X squared

• Square root of X

• Cube root of X

• Fourth root of X

When no index is specified, which root is assumed by default?

• Fourth root

• Square root

• Fifth root

• Cube root
