Solve for X : Log10 (X - 10) = 1

Solve for x : log₁₀ (x - 10) = 1

Sum

log₁₀ ( x - 10 ) = 1
⇒ log₁₀ ( x - 10 ) = log₁₀10
⇒ x - 10 = 10
⇒ x = 10 + 10
⇒ x = 20.

Express in terms of log 2 and log 3 : log 36

Express in terms of log 2 and log 3:

log 144

Express the following in a form free from logarithm:
a log x - b log y = 2 log 3

Prove that : `2"log" 15/18 - "log"25/162 + "log"4/9 = log 2 `

Find x, if : x - log 48 + 3 log 2 = `1/3`log 125 - log 3.

Solve for x : log (x + 5) + log (x - 5) = 4 log 2 + 2 log 3

If log 2 = 0.3010 and log 3 = 0.4771; find the value of : log 25

Solve for x :
`log 225/log15` = log x

State, true or false :
log x x log y = log x + log y

If log₁₀ 8 = 0.90, find the value of:

log₁₀ 4
