C. √10 is an irrational number.

Irrational numbers cannot be represented by a simple fraction.

8/5 is a simple fraction, making it a rational number. √4 is 2, and 2 is a rational number. √64 is 8 which makes it a rational number. However, √10 cannot be simplified; therefore, it cannot be represented by a simple fraction.
