Question

Me ajudem com essa questões?​

Answer 1

Resposta:

5)$-4\sqrt{3}$

6)$3\sqrt{3}$

Explicação passo-a-passo:

5)

$2\sqrt{3}+ 2\sqrt{12}-2\sqrt{75}\\2\sqrt{3}+ 2\sqrt{4*3}-2\sqrt{3*25}\\2\sqrt{3}+2*2\sqrt{3}-2*5\sqrt{3}\\2\sqrt{3}+4\sqrt{3}-10\sqrt{3}\\-4\sqrt{3}$

6)

$2\sqrt{3}+5\sqrt{12}-3\sqrt{27}\\2\sqrt{3}+5*2\sqrt{3}-3\sqrt{3*9}\\2\sqrt{3}+10\sqrt{3}-3*3\sqrt{3}\\12\sqrt{3}-9\sqrt{3}\\3\sqrt{3}$
