Question

Find the indicated derivative and simplify
d/dx[7x^3-3x^2/3squarerootx^2]

Answer 1

Is it:
\[\large \frac{7x^{3}-3x^{2}}{3\sqrt{x^{2}}} \]?

Answer 2

simplfy the problem by using the index laws

\[7x^3/3(^2)^{-12/} - 3x^2/3(x^2)^{-1/2}\]

simplifies to
\[7/3x^2 - x\]

its now a bit easier to find dy/dx

Answer 3

oops got it wrong it should be simplified to

\[7x^2/3 - x\]

Answer 4

use the formula dy/dx=u/v,,,,,,,=v(d/dx(u))-u(d/dx(v))all over v^2
where y respect to x
