I'm sorry but could you be a little more specific? @Crystal_Bliss

anonymous · Answer

Clarification: is this what your expression actually looks like?
$$4^{3} \sqrt{3x} + 5^{3 } \sqrt{10x}$$

anonymous · Answer

Yes. I wasn't sure how to write it @Cardinal_Carlo

anonymous · Answer

Well, anyway it's still D not possible to simplify because of the operation. That is, both values were added instead of being multiplied/divided. Also, neither of the two have anything in common, so as it is, it cannot be simplified.
