Simplify the square root of an expression with four variables

The video tutorial explains how to handle variables separately when dealing with square roots. It demonstrates rewriting expressions using power rules to simplify them. The process involves expressing terms as squares to easily take square roots, resulting in simplified expressions outside the radical. The tutorial concludes with a simplified expression and remaining terms under the radical.

What is the initial step when dealing with variables under square roots?

• Multiply all variables together

• Ignore the exponents

• Treat each variable separately

• Combine all variables into one expression

How can you rewrite A to the 7th power to facilitate taking the square root?

• A to the 6th times A

• A squared times A to the 5th

• A cubed squared times A

• A to the 7th squared

What is the purpose of rewriting B to the 18th as B to the 9th squared?

• To apply the power rule for square roots

• To simplify addition

• To make it easier to multiply

• To reduce the exponent

After taking the square root of the squared terms, what remains under the radical?

• A and B

• C and D

• A and D

• B and C

What is the result of taking the square root of C squared squared?

• C to the 4th

• C squared

• C cubed

• C
