Answer:
Yes. Square root of 2 is an irrational number. It is certainly a Real Number.
Step-by-step explanation:
It is called a real root if it is also a real number.
For example:
x2−2=0
has two real roots:
√2≈1.414
−√2≈−1.414
On the other hand:
x2+2=0
has no real roots, since x2≥0 for any real number x.
It does have roots, but they are non-real complex numbers, specifically √2i and −√2i.
