Question

Calculati suma, diferenta, produsul si catul numerelor
x=√300+2√192-3√675-√108
y=√432+2√588-3√1200+15√12

Answer 1

$x= \sqrt{300} +2 \sqrt{192} -3 \sqrt{675} - \sqrt{108}$
$x= 10\sqrt{3} +2*8 \sqrt{3} -3*15 \sqrt{3} -6 \sqrt{3}$
$x= 10\sqrt{3}+16 \sqrt{3} -45 \sqrt{3} -6 \sqrt{3}$
$x=-25 \sqrt{3}$

$y= \sqrt{432}+2 \sqrt{588} -3 \sqrt{1200}+15 \sqrt{12}$
$y=12 \sqrt{3} +2*14 \sqrt{3}-3*20 \sqrt{3} +15*2 \sqrt{3}$
$y=12 \sqrt{3} +28 \sqrt{3}-60 \sqrt{3}+30 \sqrt{3}$
$y=10 \sqrt{3}$

SUMA:
x+y=$-25 \sqrt{3}+10 \sqrt{3}=-15 \sqrt{3}$

DIFERENTA:
x-y=$-25 \sqrt{3}-10 \sqrt{3}=-35 \sqrt{3}$

PRODUSUL:
x*y=$-25\sqrt{3}* 10\sqrt{3} = -250\sqrt{3}$

CATUL:
x:y=$-25\sqrt{3}: 10\sqrt{3} =-2.5$
