b) √50+√18-√8
​

Answer 1

$3\sqrt{5}+\sqrt{5}-6\sqrt{5}\\\\=-2\sqrt{5}\\\\\\\\\sqrt{5}\cdot \:0+\sqrt{1}\cdot \:8-\sqrt{8}\\\\=0\cdot \sqrt{5}+1\cdot \:8-\sqrt{8}\\\\=0+8-2\sqrt{2}\\\\=8-2\sqrt{2}$

Answer 2

Resposta:

a) 3√5+√5-6√5 =${ \red{ -2√5}}$

$a) 3√5+√5-6√5 \\ 3√5+1√5-6√5 \\ (3+1-6)√5 \\ { \red{-2√5}}$

b) √50+√18-√8= ${ \red{6√2}}$

$b) √50+√18-√8 \\ 5√2+3√2-2√2 \\ { \red{6√2}}$
