The expression involves two radicals:

[ \sqrt[3]{2} + \sqrt[5]{4} ]

These terms represent two different irrational numbers, and they cannot be simplified further or combined directly. Each radical stands alone. Here's the approximate decimal evaluation of the expression:

$\sqrt[3]{2} \approx 1.260$ $\sqrt[5]{4} \approx 1.319$

So, the sum is approximately:

$1.260 + 1.319 \approx 2.579$
