Question

Find y' and simplify

y=3x^-2+2x^3+5

Answer 1

U know
y'=dy/dx
Right?

Answer 2

Differentiation of y with respect to x

Answer 3

Do u know
dx^4/dx=4*x^3

Answer 4

dx^-3/dx=-3*x-4

Answer 5

One more thing is
d(4)/dx=0

Answer 6

Because differentiation of any constant is equal 0

Answer 7

\[y=3x^{-2}+2x^3+5\]
\[y'=(3x^{-2})'+(2x^3)'+(5)'\]

use \((ax^n)'=anx^{n-1}\)
