Solve for x log base x of 49=2
Problem
Solution
Identify the logarithmic equation and its base definition. The equation
(log_b)(a)=c is equivalent to the exponential formbc=a Rewrite the equation in exponential form by moving the base
x to the other side.
Solve for
x by taking the square root of both sides.
Check the constraints for the base of a logarithm. The base
x must be positive (x>0 and not equal to 1 (x≠1 .Exclude the negative solution
x=−7 because it does not satisfy the logarithmic base requirements.
