Hello would gratefully appreciate help on the following question, also would you be able to guid me through how you got the answers
thank you

Find dy/dx of the following:
1) y=3^(3x-1) + (1-2x)In(1-2x)
2) y= 2x-1 -log4(x+1)
3x+4
3)
y= e^x (2x+1)^1/2
4) intergrate and differentiate:
xIn(x+1)
I presume:
I, personally, never remember the formula for taking the derivative of a log function. What I do remember is the change of base formula:
(This comes in very handy doing logs on my calculator.)
So I'm going to convert into a term, which we know how to take the derivative of.
Thus
So back to your problem:
