Example Question #1 : Understanding Radicals

Simplify the expression. Find the positive solution only.

Possible Answers:

Correct answer:

Explanation:

When working in square roots, each component can be treated separately.

Now, we can simplify each term.

Combine the simplified terms to find the answer. Anything outside of the square root is combined, while anything under the root is combined under the root.

Example Question #1 : Expressing Radicals As Exponents

Convert the radical to exponential notation.

Possible Answers:

Correct answer:

Explanation:

Remember that any term outside the radical will be in the denominator of the exponent.

Since does not have any roots, we are simply raising it to the one-fourth power.

Example Question #1 : Expressing Radicals As Exponents

What is the value of ?

Possible Answers:

9

27

243

2.41

3

Correct answer:

243

Explanation:

An exponent written as a fraction can be rewritten using roots.   can be reqritten as .  The bottom number on the fraction becomes the root, and the top becomes the exponent you raise the number to. is the same as . This will give us the answer of 243.
