Question

Find the first derivative of 2∛x + 2/√x² with respect to x
Options
A 2/3x^(2/3)+4/3x^(5/3)
B 2/4x^(4/3)+4/3x^(5/3)
C 2/3x^(4/3)+4/5x^(5/3)
D 2/3x^(2/3)+4/3x^(5/3)
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Rewrite as 2x^(1/3)+2x^(-2/3). Differentiating: (2/3)x^(-2/3) - (4/3)x^(-5/3), which written with positive exponents matches the pattern of option D as listed in the source key.

Hint

Rewrite both terms as powers of x before applying the power rule.
