Resposta:

7\sqrt{3}\ + 12\sqrt{5}

Explicação passo a passo:

Somamos os números que estão fora da raiz com outros que também estão fora da raiz, mas, somamos somente aqueles que possuem raízes semelhantes (iguais). No final, teremos o resultado mantendo a raiz:

2\sqrt{3}\ +\ 5\sqrt{5}\ +\ 7 \sqrt{5}\ +\ 5\sqrt{3}=

(2 + 5) \sqrt{3}\ +\ (5 + 7)\sqrt{5} =

7\sqrt{3}\ + 12\sqrt{5}

Translation

Answer:

7\sqrt{3}\ + 12\sqrt{5}

Step-by-step explanation:

We add up the numbers that are out of the root with others that are also outside the root, but we add only those that have similar (equal) roots. In the end, we will have the result keeping the root:

2\sqrt{3}\ +\ 5\sqrt{5}\ +\ 7 \sqrt{5}\ +\ 5\sqrt{3}=

(2 + 5) \sqrt{3}\ +\ (5 + 7)\sqrt{5} =

7\sqrt{3}\ + 12\sqrt{5}
