What is Meant by Multiplying Radicals?

In mathematics, radical is defined as an expression which contains an expression with the radical symbol (√). The number present inside the number is called the radicand whereas the small number which is present outside of the radical symbol is called the index. For example, 3√8. Here 3 is the index, and 8 is the radicand. The radical can be a square root, cube root, or the higher order of nth root. The radicals are generally used to remove the exponents. While multiplying the radicals, it follows the product rule. When the radicals are multiplied with the same index number, multiply the radicand value and then multiply the values in front of the radicals (i.e., coefficients of the radicals). The product rule for the multiplying radicals is given by

Multiplying Radicals Examples

Example 1: 

Simplify 2 ³âˆš27 × 2 ³âˆš8 

Solution:

Given: 2 ³âˆš27 × 2 ³âˆš8 

Here, both the multiplicand and the multiplier has a radical with the same index number (i,e., 3).

So, by using the product rule, it becomes

2 ³âˆš27 × 2 ³âˆš8 = 4 ³âˆš(27 × 8)

= 4 ³âˆš216

Take the cube root of 216, we get

= 4 (6) = 24

Therefore, 2 ³âˆš27 × 2 ³âˆš8 =  24.

Example 2:

Determine the value of 4 √25 × 2 ³âˆš125

Solution:

Given: 4 √25 × 2 ³âˆš125

Since the index value of multiplier and the multiplicand are different, simplify the multiplicand and multiplier separately, and then multiply it

We know that √25 = 5, and ³âˆš125 = 5

4 √25 × 2 ³âˆš125 = 4 (5)× 2(5)

=20×10

= 200

Hence, 4 √25 × 2 ³âˆš125 = 200
