anonymous · Answer

I cant figure out the irrational number

welshfella · Answer

7.7^2 = 59.29
7.9^2 = 62.41

an irrational number would be square root of  a number between these 2 
- say sqrt 61

freckles · Answer

well pi is approx 3.14 
what can you add to 3.1 to get 7.7
well 7.7-3.1=4.6
so another way to pick a irrational number between the given numbers is to say
pi+4.6
