f'(x)  =  -x⁻⁴(15 + 6x)    यदि  f(x)  =  x⁻³(5 + 3x)

Step-by-step explanation:

f(x) = xⁿ  => f'(x) = nxⁿ⁻¹

f(u)f(v)  = f(u)f'(v)  + f(u)'f(v)

f(x)  =  x⁻³(5 + 3x)

 f'(x)  =   x⁻³(5 + 3x)'  + (x⁻³)'(5 + 3x)

=>  f'(x)  =   x⁻³(0 +3)'  + (-3)(x⁻⁴)(5 + 3x)

=>  f'(x)  =   3/x³   - 3(3x + 5)/x⁴

=>  f'(x)  =   (3x  - 9x - 15)/x⁴

=> f'(x)  =  -(15 + 6x)/x⁴

=> f'(x)  =  -x⁻⁴(15 + 6x)

f'(x)  =  -x⁻⁴(15 + 6x)    यदि  f(x)  =  x⁻³(5 + 3x)
