Answer 1

Resposta:

Explicação passo a passo:

$a) -5\sqrt{9}+2\sqrt{169}\\\\5\sqrt{9} = 15\\2\sqrt{169} = 26\\-15+26=11$

$\\b) 10\sqrt{2}+\sqrt{2}-\sqrt{2}=10\sqrt{2}$

$c) \sqrt{18}+2\sqrt{50}\\\\\sqrt{18} = 3\sqrt{2} \\\\2\sqrt{50} = 10\sqrt{2}\\\\3\sqrt{2}+10\sqrt{2}\\\\3\sqrt{2}+10\sqrt{2}=13\sqrt{2}$
