The approximation of √0.8-√0.1 is between? Choose the correct choice from the following.
A) 1/5 and 1/4 B) 1/4 and 1/3 C) 1/3 and 1/2 D) 1/2 and 2/3 E) 2/3 and 1
√(0.8 )– √0.1   Let’s square this expression: 0.8 + 2√0.08 + 0.1 = 9/10+(4√2)/10   √2 is approximately 1.4 and we have (9-5,6)/10=3,4/10=34/100   Now take root of this: √(34/100)   √34 is close to 6 and our expression lies between 1/2 and 3/5=
