Com cálculo pfv!!!!!!!!!!

Answer 1

Fatorar e simplificar

colocar os termos similares em evidencia e somar os demais

$a) \\\sqrt{200} -\sqrt{72} +\sqrt{32} \\\sqrt{10^2.2}  - \sqrt{6^2.2}  + \sqrt{4^2.2} \\10\sqrt{2} -6\sqrt{2}+4\sqrt{2}\\(8\sqrt{2})/4\\2\sqrt{2}\\b)\\\sqrt{3} + 3\sqrt{3} + 4\sqrt{3}\\(8\sqrt{3})/5\\\\c)\\(10^{-4} )^2:(10^{-3})^3\\10^{-8} : 10^{-9}\\10^{8-(-9)} = 10^1 = 10\\\\d)\\(5.(5^2)^2.5^3)/(5^2)^4\\(5.5^4.5^3)/5^8\\5^8/5^8 = 1$

Espero ter Ajudado ;)
