Question

simplifique o radical e efetue a operacao √98-√18-5√32

Answer 1

$\sqrt{98} - \sqrt{18} - 5 \sqrt{32} = \sqrt{2*49} - \sqrt{2*9} - 5 \sqrt{x} 2*16$
$\sqrt{2* 7^{2} } } - \sqrt{2* 3^{2} } - 5 \sqrt{2* 4^{2} } = 7 \sqrt{2} - 3 \sqrt{2} - 5*4 \sqrt{2}$
$\sqrt{2} *(7-3-5*4) = \sqrt{2} * (7-3-20) = \sqrt{2} *(-16) = -16 \sqrt{2}$
