Question

(5√3+√5)totul la a 2 -5√5×√12 cu tot cu rezolvare

Answer 1

$(5 \sqrt{3}+ \sqrt{5}) ^{2} =3* 5^{2} +5+10\sqrt{3} \sqrt{5}=80+ 10\sqrt{15}$
$5 \sqrt{5}* \sqrt{12}=10 \sqrt{5} \sqrt{3} =10 \sqrt{15}$
$(5 \sqrt{3}+ \sqrt{5} ) ^{2}-5 \sqrt{5} * \sqrt{12}=80+10 \sqrt{15}-10 \sqrt{15} =80$

Answer 2

75+2×5√3×√5+√5 -10√15
75+10√15+5-10√15
80
