Question

root4 is a irrational number true and false​

Answer 1

It's false. The square root of 4 (or √4) is 2, and 2 is a rational number.

Explanation:

What number multiplied by itself equals 4? It's 2 right, so the square root of 4 is 2. 2 is a rational number because it can be expressed as a fraction: 2/1.

Irrational numbers like π or √2 can't be expressed as fractions.
