Question

como eu somo V32-V50+V98-V18 ​

Answer 1

V32-V50+V98-V18

=-V18+V80

=V62

Answer 2

Oi...

$\sqrt{32}~-~\sqrt{50}~+~\sqrt{98}~-~\sqrt{18}$

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

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

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

$(11-8)\sqrt{2}$

$3\sqrt{2}$

Espero ter ajudado.
