Question

Which expression is irrational?

Answer 1

Answer:

$\sqrt{10}$

Step-by-step explanation:

An irrational number can't be written as a simple fraction or ratio.

Therefore, the expressions 8/5, $\sqrt{4}$, and $\sqrt{64}$ are rational.

Why?

This is because 8/5 = 1.6, $\sqrt{4}$ = 2, and $\sqrt{64}$ = 8. Since all of the expressions can be simplified to set numbers (that can then be converted to fractions or ratios) the answer is $\sqrt{10}$.
