The square root of 10 is an irrational number, because it continues endlessly and without pattern in decimal form.

There is no real number [square] root of a negative number. There is a real cube root and a real fiftth root etc, but root, by itself, implies square root.

The square root of any positive real number (as in this case) is a real number. (Such square roots are usually irrational.)The square root of a negative real number, such as the square root of -15, is an imaginary, and therefore also a complex, number.

sqrt 90 = sqrt 9 x sqrt 10 = 3 root 10. Root 10 is irrational so sqrt 90 is irrational.
