is the square root of 11 a rational number

Question

I'm having trouble with square root and rational and irrational numbers!!

Answer 1

√11=3.31662479...is an irrational number, not a rational number; it is a never-ending and non-repeating decimal; it can not be put in the form a/b where a and b are integers and b≠0

the square root of any number that is not a perfect square is irrational:

√2, √3,√5, √6, √7, √8, √10, √11, √12, √13, √14, √15, √17, √18, √19,... are all irrational numbers

√4, √9, √16, √25, √36, √49, √64, √81... are all rational numbers

Answer 2

Short answer:  No

 

The square root of 11 is not equal to the ratio of two integers, and therefore is not a rational number.
