a) 3√2-4 = 3 * 1,414 - 4 = 4,242 - 4 = 0,242
2√3-2 = 2 * 1,732 - 2 = 3,464 - 2 = 1,464
√13 = 3,605
2√7 = 2 * 2,645 = 5,29
5+√3 = 5 + 1,732 = 6,732
3√2 - 4 , 2√3 - 2, √13, 2√7, 5 + √3
b) √234- 11 = 15,297 - 11 = 4,297
√129 - 6,5 = 11,357 - 6,5 = 4,857
√18+1,1 = 4,242 + 1,1 = 5,342
3(√17-2,1) = 3√17 - 6,3 = 3 * 4,123 - 6,3 = 12,369 - 6,3 = 6,069
√18 + √7 = 4,242 + 2,645 = 6,887
√234, √129, √18 + 1,1, 3(√17 - 2,1), √18 + √7
