a) |-3|+|+2|+|(-1)²⁰¹¹| = |-3|+|+2|+|-1| = 3 + 2 + 1 = 6
b) |√2-1,4|+|√2-1,5| = √2 - 1,4 + 1,5 - √2 = √2 - √2 + 1,5 - 1,4 = 0,1
c) -√2 - √(-2)² + |1-√2| + 2|√8-3| + |-√2|² - |-4√2| =
= -√2 - √4 + √2 - 1 + 2(3 - √8) + (√2)² - 4√2 =
= -√2 - 2 + √2 - 1 + 2(3 - 2√2) + 2 - 4√2 =
= -√2 - 2 + √2 - 1 + 6 - 4√2 + 2 - 4√2 =
= -2 - 1 + 6 + 2 - 4√2 - 4√2 =
= 5 - 8√2
