Question

Is x^2 = 144 rational or irrational

Answer 1

Answer:

The answer is that x^2=144 is rational

Answer 2

Answer:

The roots are rational

Step-by-step explanation:

Given

x² = 144 ( take the square root of both sides )

x = ± $\sqrt{144}$ = ± 12 ← both rational

A rational number can be expressed in the form

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

12 = $\frac{12}{1}$ ← thus rational

- 12 = $\frac{-12}{1}$ ← thus rational
