Simplify each expression to its lowest terms to find if each number is rational or irrational.
A. √A
Since a specific value of A is not provided, then the expression √A represents the square root of a number but we can't know if it is rational or not.
B. √35
Since √35 is already written in its lowest terms, then it is an irrational number.
C. √49
Since 49=7^2
