Simplifying Expressions with Square Roots

The video tutorial explains how to simplify the expression 3 times the square root of 200x to the third. It begins by factoring 200 and rewriting the expression under a single radical sign. The instructor then breaks down the expression into simpler parts, evaluates the square roots of individual terms, and finally combines the results to achieve the simplest form of the expression, which is 30x times the square root of 2x.

What is the first step in simplifying 3 times the square root of 200x to the third?

• Add 100 to 200

• Divide 200 by 3

• Factor out 200

• Multiply by x
