Question

(raiz de 12+raiz de 3 - raiz de 48)elevada a 2

Answer 1

(raiz de 12 + raiz de 3 - raiz de 48)²=
(3,464 + 1,73 - 6,93)²=
(-1,736)²=
3,013

Answer 2

$( \sqrt{12}+ \sqrt{3}- \sqrt{48})^2 = ( \sqrt{2^2*3}+ \sqrt{3}- \sqrt{2^2*2^2*3)} ^2 = (2\sqrt{3}+ \sqrt{3}-4 \sqrt{3} } )^2 (-1 \sqrt{3})^2 = 1 \sqrt{9} = 1*3 = 3$
