Simplification: √ 18 - √ 8; (√ 3 + 1) & # 178; Calculation: (√ 2 + 1) (√ 2-1); √ 16 + √ 0.25 - & # 179; √ 27; √ 20 + √ 5-2 √ 5; √ 12 + √ 48-3 √ 1 / 3

Simplification
√18-√8=3√2-2√2=√2
(√3+1)²=4+2√3
calculation
(√2+1)(√2-1)=(√2)^2-1=1
√16+√0.25-³√27=4+0.5-3=1.5
√20+√5-2√5=2√5+√5-2√5=√5
√12+√48-3√1/3=2√3+4√3-√3=5√3
