Simplifying Expressions with Exponents

The video tutorial explains how to simplify an expression by first applying negative exponents, converting them to positive exponents, and then rewriting the expression using rational exponents in radical form. It further simplifies the radicals to their basic form and concludes with the final simplified expression.

What is the first step in simplifying an expression with a negative exponent?

• Divide the terms

• Multiply the terms

• Add the exponents

• Apply the negative exponent to each term
