Short Answer

Expert verified

The equation does not belong to the other three is n鈭�16=29.

Step by step solution

01

Step 1. Write the given information. 

Given equations:

Here unknown variables are n.

To determine: The equation does not belong to the other three.

02

Step 2. Solving for an unknown variable.

Let the number be n.

n+14=27n=27鈭�14n=1312+n=25n=25鈭�12n=13n鈭�16=29n=29+16n=45n鈭�4=9n=4+9n=13

03

Step 3. Identify the different equations.

Only n鈭�16=29has a different solution

Thus, the equation not belong to the other three is n鈭�16=29.
