solve the logarithmic equation. be sure to reject any value of x that is not in the domain of the orginal logarithmic expression.
In square root of x+2=2 (If I try to make the square root sign it will not come out right so I wrote it out instead)
What is the exact solution.
A. The solution set is {?}
B. There are infinitely many solutions?
c. There are no solutions?

sqrt(x+2) = 2. sqrt means Square Root.
Square both sides:
x + 2 = 4
X = 2.

Correction:
Ln sqrt(x+2) = 2.
Exponential form:
sqrt(x+2) = e^2
Square both sides:
x + 2 = e^4
X = e^4  2.
X = 54.60  2 = 52.60.
