The square of a real number is always a real 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.
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.
The square roots of any positive real number are a positive and a negative real number. The square roots of any negative real number are a positive and a negative imaginary number. The square roots of any imaginary number or any complex number are two complex numbers.
The unique nonnegative square root of a nonnegative real number. For example, the principal square root of 9 is 3, although both -3 and 3 are square roots of 9.
The square of a real number is always positive no matter which real number you start with. Therefore, a negative number squared is positive. For example: 2 * 2 = 4, -2 * -2 = 4.
the square root of 2
The square of a real number is always a real number.
The short answer is "Nothing". In the complex domain, the number of nth roots of any real number is n. Every non-negative real number has 2 square roots. Every real number has 3 cube roots. Every non-negative real number has 2 real square roots and 2 imaginary ones. and so on. So what?
Square root of (2) Pi
The square root of 2 is real number but it is not rational number because it can't be expressed as a fraction.
No. "Pi", "e", and the square root of 2 are all real and irrational.
It is a real number in the sense that it is an irrational number which can't be expressed as a fraction and its length is 5 times the square root of 2
I thought it was real... square of -x is the same as the square of +x
Pi, e, square root of 2, -sqrt(3), log(2). These are all examples of real irrational numbers.
Yes. The square root of 4 is 2, because 2 times itself is 4.
