b)|⅓-½| = 0
c) |√3-2| = √3 -2
d) |2√3-3√2| = 2√3-3√2
e) 1+|1-√2|
f) 2√3-|3-2√3| = 2√3- 3 + 2√3- = 4√3 -3
g) |3-π|-π = 3-π - π =3 -2π
h) |√3-2|+|1-√3|= √3-2+1-√3= 1
a) √x²=5
x = 5 lub x = -5
b) √(x-2)²=3
x-2 = 3 lub -x + 2 = 3
x = 5 -x = 1
x = 1
c) √x²+4x+4=1
√(x + 2)² = 1
x+2 = 1 lub -x -2 = 1
x = -1 -x = 3
x = -3
d) √1-2x+x²=6
√(1-x)² = 6
1-x = 6 lub -1+x = 6
-x = 5 x = 7
