Question

Calculaţi:
$\sqrt{(2 \sqrt{3} - 4)^{2}} - \sqrt{(1 - \sqrt{3})^{2}$ =
$\sqrt{1+ \frac{1}{2}} + \sqrt{2+\frac{2}{3} }$ =

Answer 1

stim ca √a² = a
 deci din prima ecuatie radicalul dispare si ramane
2√3 - 4 - 1 + √3 = 3√3 -5

$\sqrt{3/2$+$\sqrt8/3$=$\sqrt3$/$\sqrt2$ + $2 \sqrt2$/$\sqrt3$  se reduc radicalii si ramane =2
