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

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 : log 4.5

Express in terms of log 2 and log 3 :
`"log"75/16 - 2"log"5/9 + "log"32/243`

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.

If log 2 = 0.3010 and log 3 = 0.4771; find the value of : log 3.6

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

If log₁₀2 = a and log₁₀3 = b; express each of the following in terms of 'a' and 'b' : log 60

If log₁₀2 = a and log₁₀3 = b; express each of the following in terms of 'a' and 'b' : log `3 1/8`

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

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