If 2 Log Y - Log X - 3 = 0, Express X in Terms of Y.

If 2 log y - log x - 3 = 0, express x in terms of y.

Sum

2log - logx - 3 = 0
⇒ logx = 2logy - 3
⇒ logx = logy²- 3log10 ...[∵ log10 = 1]
⇒ logx = logy²- log10³
⇒ logx = `"log"(y^2/1000)`
∴ x = `y^2/(1000)`.

If log 2 = 0.3010 and log 3 = 0.4771 ; find the value of : log 1.2

If log₁₀ 8 = 0.90; find the value of : log√32

If log 27 = 1.431, find the value of : log 9

Prove that : If a log b + b log a - 1 = 0, then b^a. a^b = 10

Prove that:

log₁₀ 125 = 3(1 - log₁₀2).

Simplify : log (a)³÷ log a

Simplify the following:

`3"log" (32)/(27) + 5 "log"(125)/(24) - 3"log" (625)/(243) + "log" (2)/(75)`

If log 16 = a, log 9 = b and log 5 = c, evaluate the following in terms of a, b, c: log 75

If 2 log x + 1 = 40, find: x

If x² + y² = 6xy, prove that `"log"((x - y)/2) = (1)/(2)` (log x + log y)
