Q22 / 60 · JEE Advanced 2013 (Paper 2) · Mathematics
If , then x =
If , then x =
- Correct answerA
- Correct answerB
- Correct answerC
- D
Solution
3x = 4x - 1
x = (x - 1) log3 4
x ( 1 - 2 log3 2) = -2log3 2
x log2 3 = (x - 1).2
x (log2 3 - 2) = -2
x = (x - 1) log3 4
x ( 1 - 2 log3 2) = -2log3 2
x log2 3 = (x - 1).2
x (log2 3 - 2) = -2
Hence, the correct answer is options: 'A', 'B', 'C'.
