Maths ---derivative

Differentiate each of the following functions with respect to x.
1. y = (x+1)log (3) 5x

2. y = -4x log(5) 2x

3. y = (x^4+2x)log(3) 2x

4. y = 3^ (4x-2)

5. y = log(3) ((2x-1)(4x+3))

6. If g(x)=4^(x+1) In ((x^4)+1), find f'(0) and express the answer in terms of natural logarithm.

Plx explain briefly for those questions, thx~

**log (3) 5x = log 5x base 3
