4\\sqrt{13}-6\\sqrt{13}+10\\sqrt{13}\n8\\sqrt{13}\n12\\sqrt{13}\ncannot be simplified

Explanation:

Step1: Combine like - terms

We have terms with the same radical $\sqrt{13}$. Combine the coefficients: $(4 - 6+10)\sqrt{13}$.

Step2: Calculate the coefficient

$4-6 + 10=(4 + 10)-6=14 - 6 = 8$. So, $(4 - 6+10)\sqrt{13}=8\sqrt{13}$.

Answer:

$8\sqrt{13}$
