Question

wyłącz czynnik przed pierwiastek (x,y,z >_)

√12,√28,√44,√80,√1/45,√20+√125

3√24,3√32,3√-48,3√1/81,3√-108,3√135-3√-54

Answer 1

√12 = 2√3

√28 = 2√7

√44 = 2√11

√80 = 4√5

√1/45 = 1/3 * √1/5

√20 + √125 = 2√5 + 5√5 = 7√5

3√24 = 6√6

3√32 = 12√2

3√-48 = 12i√3

3√1/81 = 3/9 = 1/3

3√-108 = 18i√3

3√135 - 3√-54 = 9√15 - 9i√6
