The value of n in the square root equation is -4

Solving equations involving square roots.

The solution to square roots equation can be determined by a step by step process. So, let's solve the equation where the square root applies to all values after the radical.

Mathematically, it can be written as:


3 -√(5-n)=√(-4-n)


√(5-n)=3 - √(-4-n)


√(5-n)=(3 - √(-4-n))^2

Take the square of the both sides to eliminate the square root.


5-n =9-6√(-4-n) +(-4-n)

Collect like terms


5-n =5-6√(-4-n) -n

Set the square root terms to zero


6√(-4-n)=0

Divide both sides by 6


√(-4-n)=0

Square both sides by 6

-4 - n = 0

n = -4
