Simplifying a radical expression using rational exponents

The video tutorial covers simplifying expressions using exponent rules. It begins with an introduction to simplifying expressions and applying exponent rules to convert expressions to rational exponents. The tutorial explains distributing exponents across multiplication and division, simplifying cube roots by rewriting numbers as powers, and further simplification techniques. It concludes with alternative methods for simplification, emphasizing the importance of checking for the simplest form.

What is the first step in simplifying the expression 64 Z^6 raised to the 1/3 power?

• Multiply the exponents directly

• Divide the exponents

• Add the exponents

• Convert it to a rational exponent

Which of the following is a correct representation of 64 as a power of another number?

• 8^3

• 4^3

• 16^2

• 2^4

What is the cube root of 64?

• 8

• 2

• 16

• 4

After simplifying 8^(2/3) * Z^(6/2), what is the resulting expression?
