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.
