Answer 2

AnswEr :

We have to express 4log(m) - log(n) as an single logarithm

Given Expression,

$\sf \: 4 log(m) - log(n)$

Power Rule of Logarithm : alog(b) = log(b^a)

$\longrightarrow \: \sf \: log( {m}^{4} ) - log(n)$

Division Rule of Logarithm : log(a) - log(b) = log(a/b)

$\longrightarrow \: \sf \: log( \dfrac{ \: \: \: {m} \: ^{4} }{n} )$

Thus,the log expression can be rewritten as log(m⁴/n)

Properties of Logarithms :

• Log(a) + Log(b) = Log(ab)

• Log_b(a) = Log(a)/Log(b)

• Log(a) - Log(b) = Log(a/b)

• b Log (a) = Log(a^b)
