Answer:
Hence, the value of n such that the given equation
holds true is: n=16.
Step-by-step explanation:
We have to find the value of n such that it make the following statement or equation true:

As we are given a square root on the variable term 'n' on left side of the equation hence , on squaring both side of the equation we obtain the value of n as:

This means:

Hence, the value of n such that the given equation
holds true is 16.
