Question

How to simplify (x-9x(x^1/2)) / (x^1/2)

Answer 1

\[x-9x \sqrt{x}/\sqrt{x}\]

Answer 2

is this \[\frac{ x - 9 x ^{3/2} }{ x ^{1/2} }\] ??

Answer 3

ok then how would you take the derivative of that ?

Answer 4

see x can be written as \[x = (\sqrt{x})^{2}\]
now take root of x common from numerator terms and cancel with denominator

Answer 5

ok thanks

Answer 6

can someone still show me how to do the derivative of it?

Answer 7

then the expression will become \[\sqrt{x} - 9 x\]

Answer 8

\[\sqrt{x}-9\sqrt{x} \right?\]

Answer 9

\[\sqrt{x}-9\sqrt{x}\] **

Answer 10

differentiation of x wrt x is 1

Answer 11

oooh wow ok i got it now!!

Answer 12

thanks !! just didnt see it lol..

Answer 13

\[\frac{ d(\sqrt{x}) }{ dx } = \frac{ 1 }{ 2\sqrt{x} }\]
