Simplifying Radical Examples

Simplifying Radicals

Simplifying radicals include the simplification of radicals denominator before performing basic mathematical operation.

Radical is a topic from Algebra which relates with the exponents. This topic includes simplification of radicals, multiplying and dividing radicals and solving radicals. Lets us find answers for radical examples in order to understand the concept of radicals.

Radical Examples

Example 1: Find the principal cube root of 125.

Solution:

125 = 5³.

Hence, the principal cube root of 125 is 5.

Example 2: Rationalize the denominator of √(15/3).

Solution:

We have to rationalize the denominator, √3.

The rationalizing factor is √3.

Multiply the numerator and denominator by √3

[√(15/3)] X [√3/√3]

Now we have,

[√(15 x 3)]/(√3)^2

(√45)/3


Hence, we have rationalized the denominator.
