Answer 1

log 15 = a and log 75 =b
then
\[\large \log_{75}45\]=

Answer 2

hint : \(\large \dfrac{15^3}{75} = 45\)

Answer 3

after that

Answer 4

Answer 5

take \(log_{75} \) for both sides of ganesh hint
so we would have
\(log_{75} \dfrac{15^3 }{75}=3 log_{75} 15-log_{75} 75\)

and use this hint to evaluate \(log_{75} 15\)
