Question
49-54 - Logarithmic Equations Solve the logarithmic equation
for x, as in Example 7.
49. log x + log(x - 1) = log(4x)
50. log, x + log,(x + 1) = log, 20
51. 2 log x = log 2 + log(3x – 4)
52. In(x - ) + In 2 = 2 In x
53. log, 3 + log,x = log, 5 + log.(x – 2)
54. log.(x + 2) + log, 3 = log, 5 + log.(2r – 3)
