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 : log 36

Evaluate the following without using tables :
log 5 + log 8 - 2 log 2

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

If log₁₀2 = a and log₁₀3 = b ; express each of the following in terms of 'a' and 'b': log 12

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

If log₁₀ 8 = 0.90; find the value of : log₁₀ 4
