Question

root x?

Answer 1

\[\sqrt{x}\]

Answer 2

?

Answer 3

What exactly are you asking?

Answer 4

differentiate it?

Answer 5

\[1\div2\sqrt{x}\]

Answer 6

Write it as:
\[\large x^{1/2}\]
then apply the chain rule.

Answer 7

OK, root x = x^1/2
d/dx x^1/2 = (1/2)x^-(1/2)
= 1/2*x^1/2
\[=\frac{\sqrt{x}}{2x}\]

Answer 8

i hav taken bio so, i don't know chain rule.

Answer 9

hw u get 1/2

Answer 10

d/dx x^y = yx^(y-1) right?
so in this case y = 1/2 (sqrt means the 1/2 power)

Answer 11

\[\huge \frac{d}{dx}=\frac{1}{2} x^{\frac{1}{2}-1} =>\frac{1}{2} x^{\frac{-1}{2}} \]

Answer 12

Yeah then put in surd form and rationalise
