Question

f(x)' √x(2x+4)

Answer 1

\[\sqrt{x}(2x+4) \ \ or \ \ \sqrt{x(2x+4)}\]

Answer 2

first one

Answer 3

First can you try it out by yourself?

Answer 4

Use the product rule

Answer 5

hmm i got :
\[2√x + 1/2√x(2x+4)\]

Answer 6

dunno how to go from there =/

Answer 7

Yes thats Right!!! :) Hope you understood :)

Answer 8

You can simplify it , 1second ..

Answer 9

\[2\sqrt{x}+ \frac{(2x+4)}{\sqrt{2x}}=\frac{2\sqrt{x}}{1}+ \frac{(2x+4)}{2\sqrt{x}}\]\[\frac{2\sqrt{x}\times 2\sqrt{x}}{1\times 2\sqrt{x}}+ \frac{(2x+4)}{2\sqrt{x}}=\frac{4x}{2\sqrt{x}}+ \frac{(2x+4)}{2\sqrt{x}}\]\[ \frac{(4x+2x+4)}{2\sqrt{x}}= \frac{(6x+4)}{2\sqrt{x}}\]Now factor out 2 from 6x+4
6x+4 =2(3x+2)\[ \frac{2(3x+2)}{2\sqrt{x}}= \frac{(3x+2)}{\sqrt{x}}\]

Answer 10

0_o

Answer 11

If you want you can rationalise \[ \frac{(3x+2) \times \sqrt{x}}{\sqrt{x} \times \sqrt{x}} = \frac{\sqrt{x}(3x+2)}{x}\]\[\frac{\sqrt{x}3x}{x}+\frac{2\sqrt{x}}{x}= 3\sqrt{x}+ \frac{ 2}{\sqrt{x}}\]
