The square root of a negative number is considered an imaginary number, denoted as "i". In this case, the square root of -3 would be √(-3) = √3 * i. Therefore, the square root of -3 is not a real number, as real numbers are those that can be represented on the number line without involving "i".
The square root of negative 36 is an imaginary number and therefore not an irrational number. For a number to be irrational it must first be real.
It is a real number, a rational number, an integer.
All irrational numbers are Real numbers - it's part of the definition of an irrational number. Imaginary numbers are neither rational nor irrational. An example of a number that is both Real and irrational is the square root of two. Another example is the number pi.
Well, first let's define a "real number." A real number is any number that's not imaginary. It can be rational or irrational. The square root of 7 is 2.64575131... and it goes on forever. This means it cannot be written as a simple fraction. We can give an estimate of the square root of 7 in a fraction form, but this is not the exact result. So, the square root of 7 is a irrational number.Since a real number can be irrational or rational, yes, the square root of 7 is a real number.
Yes it's a real number but it is an irrational number because it can't be expressed as a fraction.
It's irrational/not a real number
The square root of negative 36 is an imaginary number and therefore not an irrational number. For a number to be irrational it must first be real.
No. The square root of negative one is an example of an imaginary (not real) number. Pi is irrational, but real.
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.
No, it is not even a real number. It is an imaginary number.
All real numbers are irrational. For example, Pi is an irrational number that is a real number. Other irrational numbers can be the square root of an imperfect square.
The square root of 8 is irrational and real.
It is a real number, a rational number, an integer.
The square root of any negative number is not even a 'real' number. It's called 'imaginary', because there's no number you can multiply by itself to get a negative number. The square root of 101 is irrational.
Yes, square of 2 is a real number. Real numbers fall into 2 categories, Rational and Irrational. Square of 2 is an irrational number.
The square root of any positive, non-square number will be both real and irrational.
The square root of 100 is rational since it is not repeating. No. The square root of a negative number is not a real number, but an imaginary number, because no real number squared equals a negative number. The square root of a negative number is a so-called IMAGINARY number
