Hints for difficult problems

Irrational numbers
Exercise 1.3.1

1.Write four possible irrational numbers between 4 and 5.

Solution:

Consider the squares of 4 and 5

Square of 4 = 16 and Square of 5 = 25

We can also write 4 and 5 as

√ 16 =4 and √ 25 =5

Between and there exists

√ 17 ,√ 18 , √ 19 , √ 20 , √ 21 , √ 22 , √ 23 , √ 24
