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

Solve for x : log₁₀ (x - 10) = 1

बेरीज

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:

`log26/51 - log91/119`

Evaluate the following without using tables :
log 4 + `1/3` log 125 - `1/5`log 32

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

Solve for x : log (x² - 21) = 2.

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

Solve for x : ` ( log 128) / ( log 32 ) ` = x

If log₁₀2 = a and log₁₀3 = b ; express each of the following in terms of 'a' and 'b': log `2 1/4`

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

State, true or false :
`log x/log y` = log x - log y

State, true or false :
If `log 25/log 5 = log x`, then x = 2.
