Question

Scoateti factorii de sub radicali si apoi calculati: a) 3 radical din 8 + 5 radical din 18 - 7 radical din 50 b) 2 radical din 27- 7 radical din 3 + 6 radical din 12. VA ROG URGENTTTTTTT DAU COROANAAAAAA+ 20 DE PUNCTEEEEEEEEEEEEE

Answer 1

Răspuns:

a) -14 radical 2

b) 11 radical 3

Explicație pas cu pas:

a) 3 radical 8 + 5 radical 18 - 7 radical 50 = 3 * 2 radical 2 + 5 * 3 radical 2 - 7 * 5 radical 2 = 6 radical 2 + 15 radical 2 - 35 radical 2 = -14 radical 2

b) 2 radical 27 - 7 radical 3 + 6 radical 12 = 2 * 3 radical 3 - 7 radical 3 + 6 * 2 radical 3 = 6 radical 3 - 7 radical 3 + 12 radical 3 = 11 radical 3

Answer 2

a)3√8+5√18-7√50=6√2+15√2-35√2=-14√2

b)2√27-7√3+6√12=6√3-7√3+12√3=11√3
