If log_√27x = 2 `(2)/(3)` , find x.

If m = log 20 and n = log 25, find the value of x, so that :
2 log (x - 4) = 2 m - n.

Given : `log x/ log y = 3/2` and log (xy) = 5; find the value of x and y.

Solve for x, `log_x^(15√5) = 2 - log_x^(3√5)`.

Evaluate : `( log _5^8 )/(( log_25 16 ) xx ( log_100 10))`

Solve the following:
log ₈ (x²- 1) - log ₈ (3x + 9) = 0

If log ₃ m = x and log₃ n = y, write down
`3^(1-2y+3x)` in terms of m an n

If 2 log x + 1 = log 360, find: x

If 2 log x + 1 = log 360, find: log(2 x -2)

Express the following in a form free from logarithm:
`2"log" x + 1/2"log" y` = 1
