Why[tex]\sqrt\frac x{y}\not =\frac{\sqrt x}{\sqrt y}[/tex] ??arildno said:Lines 2-to-3 wrong.
Don't bother to post similar riddles at these forums.

Imaginary numbers are numbers that are expressed in the form of a real number multiplied by the square root of -1. They are used to represent complex numbers and cannot be represented on a traditional number line.
Imaginary numbers got their name because they were initially thought to be "imaginary" or non-existent. However, they were later found to be useful in solving mathematical problems and are now an important part of complex numbers.
Real numbers are numbers that can be represented on a traditional number line and include all rational and irrational numbers. Imaginary numbers, on the other hand, cannot be represented on a number line and are always expressed in terms of the square root of -1.
Some properties of imaginary numbers include the fact that when squared, they result in a negative real number. Additionally, they follow the same rules of arithmetic as real numbers, such as addition, subtraction, multiplication, and division.
Imaginary numbers are used in various fields of science and engineering, such as electrical engineering, quantum mechanics, and signal processing. They are also used in financial modeling and computer graphics.
