Answer 2

Ответ:

1) √56 = √4*14 = √4√14 = 2√14

2) √18 = √9*2 = √9√2 = 3√2

3) √800 = √400*2 = √400√2 = 20√2

4) √0,72 = √0,36*2 = √0,36√2 = 0,6√2

5) 1/3√288 = 1/3 * √144*2 = 1/3*√144√2 = 1/3*4√2

6) -1,2√450 = -1,2 * √225*2 = -1,2 * √225√2 = -1,2*15√2

7) -15√0,32 = -15 * √0,16*2 = -15 * √0,16√2 = -15 * 0,04√2

8) 3/14√10 8/9 = 3/14 * √14/9*7 = 3/14 * √14/9√7 = 3/14 * 2/9√7
