Math Problem Statement
log base 2 (x-1) + 1 = Log base 2 (x+3)
Solution
Let's solve the equation:
Step 1: Isolate the logarithmic terms.
First, subtract 1 from both sides:
Step 2: Express the 1 as a logarithm.
We know that , so:
Step 3: Use the logarithm subtraction rule.
The subtraction of logarithms can be expressed as the logarithm of a division:
Step 4: Set the arguments equal to each other.
Since the logarithms are equal, their arguments must be equal:
Step 5: Solve the equation.
Multiply both sides by 2 to eliminate the fraction:
Expand and simplify:
Subtract from both sides:
Add 2 to both sides:
Step 6: Check the solution.
Substitute back into the original equation:
and :
The equation holds true, so the solution is:
