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.

Exercise 8 (B) | Q 7.1 | Page 106

Express in terms of log 2 and log 3:

`log26/51 - log91/119`

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

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

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

Solve for x : ` (log 64)/(log 8)` = log x

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

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.

Given that log x = m + n and log y = m - n, express the value of log ` ( 10x ) / ( y ^ 2 )` in terms of m and n.

If log₁₀ 8 = 0.90, find the value of:

log₁₀ 4
