Given:
The two expressions are


To find:
Whether the given expression are equivalent or non-equivalent.
Solution:
If two expressions are looking different but they are equal after simplification, then they are called equivalent expressions.
The first expression is

The first expression is equal to the second expression after the simplification.
Therefore, the given expressions are equivalent.
