Question

derivadas f (X)=x2÷10

Answer 1

→ Lembrete - Regra da Potência:

⇒ $\frac{d}{dx}\left(ax^n\right)=nax^{n-1}$
==========
$f\left(x\right)=\frac{x^2}{10}\\\\\frac{d}{dx}\left(f\left(x\right)\right)=\frac{d}{dx}\left(\frac{x^2}{10}\right)\\\frac{1}{10}\cdot \frac{d}{dx}\left(x^2\right)\\\frac{1}{10}\cdot 2x\\\frac{2x}{10}\\\boxed{\bold{\frac{x}{5}}}$
