Express Log102 + 1 in the Form of Log10x. - Mathematics

Express log₁₀2 + 1 in the form of log₁₀x .

Sum

log₁₀2 + 1

= log₁₀2 + log₁₀10 ....[ ∵ log₁₀10 = 1 ]

= log₁₀2 x 10 ....[ log_am + log_an = log_amn ]

= log₁₀20.

Express in terms of log 2 and log 3 : log 4.5

Evaluate the following without using tables :
log 5 + log 8 - 2 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 (x² - 21) = 2.

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 12

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

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

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