Question
log9 (3log2 (1 + log3 (1 + 2log2x))) = 1/2. Find x.Choices:- None of the above 1 12/30 2
Solution 1
To solve the equation, we need to follow these steps:
-
We know that log base a of a equals 1. So, we can rewrite the equation as: 3log2 (1 + log3 (1 + 2log2x)) = 9^(1/2) = 3.
-
Divide both sides by 3 to isolate the inner expression: log2 (1 + log3 (1 + 2log2x)) = 1.
-
Use the property of logarithms that says log base a of a equals 1 to rewrite the equation as: 1 + log3 (1 + 2log2x) = 2^1 = 2.
-
Subtract 1 from both sides to isolate the inner expression: log3 (1 + 2log2x) = 2 - 1 = 1.
-
Use the property of logarithms that says log base a of a equals 1 to rewrite the equation as: 1 + 2log2x = 3^1 = 3.
-
Subtract 1 from both sides to isolate the inner expression: 2log2x = 3 - 1 = 2.
-
Divide both sides by 2 to isolate the inner expression: log2x = 2 / 2 = 1.
-
Use the property of logarithms that says log base a of a equals 1 to rewrite the equation as: x = 2^1 = 2.
So, the solution to the equation is x = 2.
Solution 2
To solve the equation, we need to follow these steps:
-
We start with the given equation: log9 (3log2 (1 + log3 (1 + 2log2x))) = 1/2.
-
We know that log base b of a equals c can be written as b^c = a. So, we can rewrite the equation as: 9^(1/2) = 3log2 (1 + log3 (1 + 2log2x)).
-
Simplifying 9^(1/2) gives us 3, so the equation becomes: 3 = 3log2 (1 + log3 (1 + 2log2x)).
-
Dividing both sides by 3, we get: 1 = log2 (1 + log3 (1 + 2log2x)).
-
Using the property of logarithms, we can rewrite the equation as: 2^1 = 1 + log3 (1 + 2log2x).
-
Simplifying 2^1 gives us 2, so the equation becomes: 2 = 1 + log3 (1 + 2log2x).
-
Subtracting 1 from both sides, we get: 1 = log3 (1 + 2log2x).
-
Using the property of logarithms again, we can rewrite the equation as: 3^1 = 1 + 2log2x.
-
Simplifying 3^1 gives us 3, so the equation becomes: 3 = 1 + 2log2x.
-
Subtracting 1 from both sides, we get: 2 = 2log2x.
-
Dividing both sides by 2, we get: 1 = log2x.
-
Using the property of logarithms one last time, we can rewrite the equation as: 2^1 = x.
-
Simplifying 2^1 gives us 2, so the equation becomes: x = 2.
So, the answer is 2.
