There are 2 methods
1. Take the approximate values of root 5 and root 7 and find the irrational numbers between them
Root 5 = 2.23
Root 7 = 2.64
2 values between them are
2.333356282581......
2.5815830267199.....
2. If a^2 < m^2 < b^2
a a^2 =(Root5)^2
b^2 =( Root7)^2
And m are the numbers we need to find
So m^2 lies between 5 and 7
Take any 2 values
Example - 6 and 6.5
So m = Root 6 and root 6.5
(You can take others too)

√2 =1.414........
√7 = 2.645......
Thus a rational number between √2 and √7 = 1/2(1.4+2.6 )= 1/2(5)=2.5
