f'(x) = 36x⁻¹⁰ - 12x⁻⁵ यदि f(x) = f(x) = x⁻⁴(3 - 4x⁻⁵)
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⁻⁴(3 - 4x⁻⁵)
f'(x) = x⁻⁴(3 - 4x⁻⁵)' + (x⁻⁴)'(3 - 4x⁻⁵)
=> f'(x) = x⁻⁴(0 - (-5)4x⁻⁶) + (-4x⁻⁵)(3 - 4x⁻⁵)
=> f'(x) = 20x⁻¹⁰ - 12x⁻⁵ + 16x⁻¹⁰
=> f'(x) = 36x⁻¹⁰ - 12x⁻⁵
f'(x) = 36x⁻¹⁰ - 12x⁻⁵ यदि f(x) = f(x) = x⁻⁴(3 - 4x⁻⁵)
या
f(x) = x⁻⁴(3 - 4x⁻⁵)
=> f(x) = 3x⁻⁴ - 4x⁻⁹
=> f'(x) = -12x⁻⁵ + 36x⁻¹⁰
