Question

I need this as soon as possible. Select all irrational numbers.

Answer 1

A rational number can be expressed in the form

$\frac{a}{b}$ where a and b are integers

Otherwise irrational

Note that $\sqrt{8}$, $\sqrt{10}$, $\sqrt{2}$ are all irrational

$\sqrt{}\frac{1}{16}$ = $\frac{1}{4}$ → rational

$\sqrt{}\frac{1}{8}$ → irrational

$\sqrt{}\frac{1}{10}$ → irrational

$\sqrt{}\frac{1}{4}$ = $\frac{1}{2}$ → rational

$\sqrt{}\frac{1}{2}$ → irrational
