Question

Determine dy/dx for y=5sqrt(x^3)

Answer 1

y=5sqrt(x^3)
= 5(x^(3/2))
dy/dx = 5(3/2)(x^(3/2 -1))
= 15/2 (x^1/2)

Answer 2

IsTim now you're here for math too? giggle, shiny and math?

Answer 3

y=x^n
dy/dx = nx^(n-1)

this is the property I use

Answer 4

Truly, I don't really understand what derivatives is.
@Ishaan94 Pardon?

Answer 5

The Power Rule. Ok.

Answer 6

Sorry.

Answer 7

It's ok. I don't understand (your speech and derivatives; either/or) though.

Answer 8

If you can, please describe each step thoroughly. Thank you.

Answer 9

OH well.

Answer 10

What's happening at dy/dx = 5(3/2)(x^(3/2 -1)) ?

Answer 11

Or, how did it come to that?

Answer 12

y=ax^n
dy/dx =a( nx^(n-1))

put a=1 and n=3/2

Answer 13

Uhm, sorry to ask, but could you type dy/dx = 5(3/2)(x^(3/2 -1)) in Latex (The Equation Editor)? I don't think I'm understanding it correctly.

Answer 14

@CoCoTsoi When you have time, of course.
