Question

a) √0,01 - √0,05

b)0,5 . √100 - √1/4

Answer 1

a, \(\sqrt{0,01}-\sqrt{0,05}\\ =\frac{1}{10}-\frac{\sqrt{5}}{10}\\ =\frac{1-\sqrt{5}}{10}\)

b, \(0,5\cdot\sqrt{100}-\sqrt{\frac{1}{4}}\\ =0,5\cdot10-\frac{1}{2}\\ =5-\frac{1}{2}\\ =\frac{9}{2}\)

Answer 2

a) \(\sqrt{0,01}-\sqrt{0,05}=0,1-\frac{\sqrt{5}}{10}=\frac{1-\sqrt{5}}{10}\)

b) \(0,5.\sqrt{100}-\sqrt{\frac{1}{4}}=0,5.10-\frac{1}{2}=\frac{9}{2}\)

Answer 3

a) \(\sqrt{0,01}-\sqrt{0,05}\) = \(0,1-\frac{\sqrt{5}}{10}\)

= \(\frac{1-\sqrt{5}}{10}\).

b) \(0,5.\sqrt{100}-\sqrt{\frac{1}{4}}\) = \(0,5.10-\frac{1}{2}\)

= \(5-\frac{1}{2}\)

= \(\frac{9}{2}\).
