Express the Following in a Form Free from Logarithm: 2 Log X + 3 Log Y = Log a

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

Sum

Consider the given equation
2 log x + 3 log y = log a
⇒ logx² + logy³ = log a
⇒ log x²y³ = log a
⇒ x²y³ = a

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

Express the following in a form free from logarithm:

2 log x - log y = 1

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 : log₁₀ (x - 10) = 1

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

Solve for x : `(log 81)/(log27 )` = 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

If log₁₀ 8 = 0.90, find the value of:

log₁₀ 4
