Question

1. Simplifique as expressões envolvendo radicais:
a) √3+√5+2√3-2√5. b) 4√2-3√3+√3. c) √48+√12-√27+√108. d) 2√5+3√7+√45-2√28. ​

Answer 1

Resposta:

a) 3$\sqrt{3}$+ $\sqrt{5}$-2$\sqrt{5}$    /  b) 4$\sqrt{2}$- 2$\sqrt{3}$   /  c) 9$\sqrt{3}$    /   d)5$\sqrt{5}$-$\sqrt{7}$

Explicação passo-a-passo:

a) 3$\sqrt{3}$+$\sqrt{5}$-2$\sqrt{5}$

3$\sqrt{3}$-5

b) 4$\sqrt{2}$-2$\sqrt{3\\}$

c) 4$\sqrt{3}$+$\sqrt{12}$-$\sqrt{27}$+$\sqrt{108}$

   4$\sqrt{3}$+2$\sqrt{3}$-3$\sqrt{3}$+6$\sqrt{3}$

  9$\sqrt{3}$

d) 2√5+3√7+√45-2√28

   2$\sqrt{5}$+3$\sqrt{7}$+3$\sqrt{5}$-4$\sqrt{7}$

   5$\sqrt{5}$+3$\sqrt{7}$-4$\sqrt{7}$

   5$\sqrt{5}$-$\sqrt{7}$
