Question

Help Please :)

calculate dy/dx ;

y= (x^2.7/8 + 3/x^2.7)(8x-1)

Answer 1

Use Product Rule.

Answer 2

how would i start it

Answer 3

Derivative first factor and left second one untouched. Then put sun then derivative second factor and left first one untouched.

EX: f(x) = (x^2.7/8 + 3/x^2.7) g(x) = (8x-1)
dy/dx = f'(x)g(x) + f(x)g'(x)

Answer 4

Is this clear enough?

Answer 5

yes, im just having trouble finding the derivative of the first portion of the equation.

Answer 6

.3375x^5.4-8.1 / x^3.7

Answer 7

Not sure how you got x^5.4... While taking the derivative, you basically should go from x^n to nx^(n-1)

Answer 8

oh ok.

Answer 9

what should it be? i got 2.1
