1. = √25/4 = 5/2
2. = √9 = 3
3. = 0,01 ^3 = 0,0001
4. = √6 -√(6 - 2 ) = √6√(4) = √(6 - 2) = √4 = 2
5. = (9 - 2(√3 * √5)) * (3√3 +2√5) = (9 - 2√3 * 2√5)) * (3√3 +2√5) = 27√3 - 36√5 - 40√3 + 18√5 = - 18 √5 - 13√3
6. = 3√(54/2) - (5√5/5√160) = 3√27 - 5√(-5/160) = 3 - 5√(-1/32) = 3 - 1/2 = 2 i 1/2
7. = (√3 * √4) -2(√25 * √3) = 2√3 - 2 (5√3) = 2√3 - 10√3 = -8√3
8. = 3√-8/1000 = -2/10
9. = (√3 * √5 + √3 * √7)/√3 = √5 +√7
