Question

x^2=9 is rational or irriational no.

Answer 1

Answer:

X^2=9

$x = \sqrt{9}$

$x = 3$

3 is a irrational number because we cannot write 3 in the form of p÷q.

Answer 2

Answer:

Is a rational number.

Step-by-step explanation:

⇒ $x^{2}$ = 9

⇒ $x$ = $\sqrt{9}$

⇒ $x$ = ±3.

As we know, an Irrational Number is a real number that cannot be written as a simple fraction or in  $\frac{p}{q}$ form.

+3 =  $\frac{3}{1}$

-3 =  $\frac{-3}{1}$

∴ $x^{2}$ = 9 is a rational number as it can be denoted in $\frac{p}{q}$ form.
