Given that the logarithm of the base nine of eighteen is equal to the power b of a.18 is equal to five, and the logarithm of the base 45 of 36 is obtained

Given that the logarithm of the base nine of eighteen is equal to the power b of a.18 is equal to five, and the logarithm of the base 45 of 36 is obtained

The Formula of Changing the Base with Logarithm
Convert 18^b=5 to: b=log18(5), then log36(45)=log18(45)/log18(36)
=[ Log18(5)+log18(9)]/[ log18(18)+log18(2)]=(a+b)/[1+log18(18)-log18(9)]
=(A+b)/(2-a)
