Question

indroduceti factorii sub radical:
1 supra 3 √2
3 supra 4 √5
1 supra 2 √6
6 √ 1supra 2
1 supra 2 √ 3supra 5
- 2 supra 5 √12

Answer 1

1) 1 / 3√2 = 1 / √3²·2 = 1 / √9·2 = 1 / √18
2) 3 / 4√5 = 3 / √4²·5 = 3 / √16·5 = 3/ √80
3) 1 / 2√6 = 1/ √2²·6 = 1 / √4·6 = 1 / √24
4) 6√1 / 2 = 6·1 / 2 = 6/2 = 3
5) 1 / 2√3 /5 = 1 : 2√3 /5 = 1 · 5 /2√3 = 5 / 2√3 = 5 / √2²·3 = 5 / √12
6) - 2 / 5√12 = - 2 / √5²·12 = - 2 / √25·12 = - 2 / √300,  / = supra
Sper ca ti-am fost de ajutor!
