Which number is irrational? A: √9 B: √8 C: 0.3333 D: 2/3 Answer fast please

Arisa [49]

$\sqrt{8}$ is an irrational number ⇒ answer B

Step-by-step explanation:

Let us explain the meaning of:

A rational number is a number that can be written as a fraction
An irrational number is a number that cannot be expressed as a fraction

Examples:

Rational numbers : 10 , $\frac{2}{5}$ , 0.333

Irrational numbers : π , √8 , ∛25 , (2 + √5) , $\frac{\sqrt{7}}{3}$

∵ $\sqrt{9}=3$

∵ 3 is a rational number

∴ $\sqrt{9}$ is a rational number

∵ $\sqrt{8}$

∵ There is no square root of 8

∴ $\sqrt{8}$ is an irrational number

∵ 0.3333 can be expressed as $\frac{3333}{10000}$

∴ 0.3333 is a rational number

∵ $\frac{2}{3}$ is a fraction

∵ All fractions are rational numbers

∴ $\frac{2}{3}$ is a rational number

$\sqrt{8}$ is an irrational number
