Question

Find dy/dx if y= 5x^3+2/x^2+4 +6

Answer 1

dy/dx =15x^2- 4/X^3
(not sure if im right though xD)

Answer 2

IS that 6 outside the fraction?

Answer 3

yes

Answer 4

\[y =\frac{5x^3 + 2 }{x^2+4}+6\]

Answer 5

it this the equation

Answer 6

yes

Answer 7

no

Answer 8

5x^3 is not in the fraction

Answer 9

\[y = 5x^3 + \frac{2}{x^2 +4} +6\]

Answer 10

yes

Answer 11

lols , is that the question damn i got it wrong then argh

Answer 12

mimi try again

Answer 13

lols , ok

Answer 14

\[\frac{dy}{dx} = 10x^2 - \frac{2(2x)}{(x^2+4)^2} \]

Answer 15

15x^2????? explain pls

Answer 16

isn't derivative of 5x^3 , 15x^2

Answer 17

yeah 15x^2
sorry

Answer 18

explain the fraction part

Answer 19

why multiply 2x

Answer 20

\[\frac{d}{dx}\frac{f(x)}{g(x)} = \frac{f'(x) g(x)- g'(x)f(x)}{(g(x))^2}\]

Answer 21

use this you will get the answer

Answer 22

okay thanks

Answer 23

i still have another question if you dont mind please give full solution with explanation thanks a bundle
