hello how do you differentiate these type of fuctions eg f(x) = Log to base 2 (5x-2)

 

[withoutaface]

f(x)=ln(5x-2)/ln2
f'(x)= [5/(5x-2)]/ln2
= 5/(5xln2-2ln2)

 

[FinalFantasy]

d\dx(ln x)=1\x
if u got other bases other than e just change da base like withoutaface did den u use that

 

[:: ck ::]

f(x)=ln(5x-2)/ln2

the ln2 is constant.. so yeah

and for say ln[ f(x) ]

the derivative is f'x / f(x)

just a general rule...
