Yes. The square root of 4 is 2, because 2 times itself is 4.

The square root of -1 is not a real number like -2.5, 0, or 5. Instead, it is and imaginary number, i, and i = the square root of -1. The answer is imaginary because you can never take a real number, square it, and get a negative number. However, i^2 = -1.

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.

Yes, the square root of 2 is an irrational number.

the square root of -28 is the square root of -1 time the square root of 28. The square root of -1 is not a real number, it is represented by i. The square root of 28 is the square root of 4 times the square root of 7 (4*7=28) The square root 4 is equal to 2, and the square root of 7 cannot be simplified.The answer is 2iâˆš7.

Sometimes the square root of a positive number can be irrational, as in the square root of 2 (which is a non-perfect square number), but sometimes it is a rational number, as in the square root of 25 (which is a perfect square number).

The square root of -4 is not irrational, it is imaginary. Irrational numbers are numbers that cannot be expressed as a fraction, like the square root of 2. Irrational numbers, however, are a subset of real numbers. The square root of -4 however, is not even a real number because no real number, when squared, gives -4. Therefore the square root of -4 is an imaginary number.In calculus, the root is expressed as 2i where iis the square root of -1.

The square root of a negative real number is an imaginary number.We know square root is defined only for positive numbers.For example,1) Find the square root of (-1)It is imaginary. We say that square root of (-1) is i.In fact they are not real numbers.2) Find the square root of (-4)-4 can be written as (-1)(4)Square root of 4 is 2 and square root of (-1) is iSo, the square root of -4 is 2i.Similarly, we can find the square root of other negative numbers also.Source: www.icoachmath.comAn imaginary number is defined to handle square roots of negative numbers. The imaginary unit i is defined as the 'positive' square root of -1.

No. It isn't a real number, either - it's a so-called complex number.

Pi, e, square root of 2, -sqrt(3), log(2). These are all examples of real irrational numbers.

Yes, as for example the square root of 2 is a real number but it is an irrational number that can't be expressed as a fraction.

1,2,3,4,5,6,1/2, 3/4 these are all real. the square root of negative is an unreal number.

The square of any square root is equal to the number itself. For example, the square of the square root of 2 squared is equal to 2. The square root of 10 squared is equal to 10.Similarly, the square of the square root of 2 is equal to 2.

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
