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.
The square root of 0 is 0, which is a real number.
Neither. All irrational numbers are real numbers.Using the real number system you can't take the square root of a negative number, but if you're dealing with imaginary numbers then the square root of negative 3 is the square root of 3i
no
it is but its not a rational #
Well, honey, the square root of a negative number like -9 isn't a real number because in the real number system, the square root of a negative number isn't defined. You gotta step into the world of complex numbers if you wanna play with those imaginary roots. So, in short, the square root of -9 is as real as a unicorn riding a rainbow.
The square root of seven is a real number, but it is not a whole number.
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 0 is 0, which is a real number.
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.
Of course, not only can it be a real number but it is a real number. When you take the square root times itself, the result is a number that is real.
Yes, the square root of 3 is a real number. (It is not imaginary. The square root of a negative number is imaginary.) The square root of 3 is not a rational number. It cannot be written as a fraction.
Yes. It's 9. The square root of every positive real number is a real number.
No. In general, the square root of a negative number is an imaginary number, which is not a real number.
The square root of a negative number is not real.
Yes. In general, the square root of any non-negative number is a real number.
no. is not a real number
The square root of -6400 is not a real number because the square root of a negative number is not defined in the real number system.
