Answer 1

a) |4 - √15| + |- 5| + |√15 - 3| = 4 - √15 + 5 + √15 - 3 = 4 + 5 - 3 = 9 - 3 = 6

b) |- 2 1/3| + |3 - √6| + |4 - √6| = |- 7/3| + 3 - √6 + 4 - √6 = 7/3 + 3 - √6 + 4 - √6 = 7/3 + 7 - 2√6 = 28/3 - 2√6

c) |√11 - √12| + |3 - √11| - |√12 - 3| = 2√3 - 3 - 2√3 + 3 = - 3 + 3 = 0

d) |√5 - √2| + |6 - √5| + |√2 - 1| = √5 - √2 + 6 -√5 + √2 - 1 = 6 - 1 = 5
