Question

$d \div dx1 + 1 \div x {}^{2}$

Answer 1

calculus differentiation problem.

$\frac{d}{dx} (1 + \frac{1}{x^2})\\\\=\frac{d}{dx}1 + \frac{d}{dx}x^{-2}\\\\=0+ (-2)*x^{-3}=-\frac{2}{x^3}$

answer : - 2 /x³

Answer 2

Question :

d ÷ dx¹ + 1 ÷ x²

Answer :

=> d/dx(1 + 1/x²)

=> d/dx1 + (d/dx)x^-2

=> 0 + (-2) × x^-3

=> - 2/x³
