Help on Adding and Subtracting Radicals

-->

Let me help you in understanding adding and subtracting radicals.

Introduction for adding and subtracting radicals:

Radicals are the inverse operations of an exponent. A radical is an expression that conveys the square roots, cube roots etc.

Solving the Adding and Subtracting Radicals:

Example 1: Adding and subtracting radicals for the following equation: √36+ √25

Solution:

The above radicals can be added by simplification. Since the √36 is 6 and √25 is 5, it can be added easily now.

Now √36+ √25 = 6 + 5 = 11 is the answer.

Now subtraction is also a simple way.

√36 - √25 = 6 - 5 = 1 is the answer.

The radical expression can also solve like the above case. If we have a variable within the root then we can solve the variable online by destruction the root of the variable.

Example 2: solve the adding and subtracting radicals for the following equation: √ x = 6

Solution:

Squaring on equally sides we find (√ x)² = (6)²

x = 36.
