Kindly help me with this questions.

Obtain the derivatives for the following funtions using the delta method

1.y=3/4

2.y=20x^3-12x^2+4x-7/18

Obtain the derivatives below using rules of differentiation

1.55x^15-11e^x2+8lnx^4+8x^-15-3/4x^5/7

2.y=(2x^3-4x^2)ln(x^4-7x^2)

3.y=(6.8ex^3+4x^2)/(9ln(x^2-7x))

4.y=(3e^(4x-10)4(lnx^3-2x)^7
