Now this case is different, when we want to solve \(\sqrt 3\), and we notice that 2 is positive, so we know the square root can be solved. But, 2 is NOT a perfect square.Hence, to solve \(\sqrt 2\), we know it exists, but we can not write it exactly. Indeed, we can ...

What is a real number? Imaginary Numbers: Imaginary numbers are also called complex numbers. When imaginary numbers are squared, the result is a negative number. Imaginary numbers are used in certain calculations, such as quadratic equations. They are the result of a real number multiplied by i...
Sqrt is square root. While it's possible to calculate the square root of a number by hand, it may be easier to use a calculator to perform this operation. Sum is short for summation, which is adding a sequence of numbers. For example, sumX is the total of all the X values and sum...
