An expression that contains root values, such as Square roots, cube roots are known as Radicals. For example: √ (p + q), and 3√ (p + q). The value 2 means square root, 3 means Cube root and so on. Radicals are represented by the symbol '√'. Here we will discuss process of Adding Unlike Radicals.
Step 1: First we take two unlike radicals. Like √ 4 + 5√ 4.
Step 2: In the given expression find the common term if present.
= √ 4 + 5√ 4, In this number '1' and '5' are common in both the term. So put like term together.
So we can write the expression as:
= (1 + 5) √ 4;
= 6√ 4.
Suppose we have another expression 2 √6 + 4 √8 + √6 + 5 √8, Now we have to add radical values given in the expression.
Here also we have to apply the same above procedure to add radicals.
In this expression two pairs are same. So we can write them as:
= 2 √6 + 4 √8 + √6 + 5 √8;
= 2 √6 + √6 + 4 √8 + 5 √8,
Now find common term in expression.
= (2 + 1) √6 + (4 + 5) √8, now we can easily add the radicals.
= 3 √6 + 9 √8. This is how we can add unlike radicals.

Radicals are used to get Square root of a number. It is very simple to learn multiplying unlike Radicals. In order to learn multiplication of Unlike Radicals let us understand the radicals first. Radical may be Like Radicals or unlike radicals.
We represent radicals by the sign '√'. This sign is used to denote radical of a number. The number which is over radical sign is index of radical and number which is under radical sign is called radicand. We can get square root of both positive and negative number.
Now let us understand the multiplication of radicals: Multiplication of unlike radicals is same as multiplication of like radicals. If two radicals are different in their radicands then they are called unlike radicals. And when two radicals are different in their index value then also we call them unlike radicals.
