Cho $f\left( x \right) = {x^2}.\sqrt[3]{{{x^2}}}$ Giá trị của $f'\left( 1 \right)$ bằng:

\(D = \mathbb{R}\backslash \left\{ { - 1;4} \right\}\).     

\(D = \mathbb{R}\).

\(D = \left( { - \infty ; - 1} \right) \cup \left( {4; + \infty } \right)\).

\(D = \left( { - \infty ; - 1} \right] \cup \left[ {4; + \infty } \right)\).

\(y = {x^5}\)

\(y = {x^{ - 1}}\)

\(y = {x^{\sqrt 2 }}\)

\(y = {\left( {{x^{\sqrt 2 }}} \right)^2}\)

\(x > 0\)

mọi \(x\)

\(x < 1\)

\(x \ne 0\)

\(y' = \dfrac{4}{3}{x^{ - \frac{1}{3}}}\)

\(y' = \dfrac{4}{3}{x^{\frac{1}{3}}}\)
