Question

Is x^2 = 144 rational or irrational

Answer 1

The answer is that x^2=144 is rational

Answer 2

The roots are rational

Explanation:

Given

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

x = ±
`√(144)` = ± 12 ← both rational

A rational number can be expressed in the form

`(a)/(b)` where a and b are integers.

12 =
`(12)/(1)` ← thus rational

- 12 =
`(-12)/(1)` ← thus rational
