The square root of a number has the exponent of 1/2. Thesquare root formulais used to find the square root of a number. We know theexponent formula:n√xxn= x1/n. When n = 2, we call it square root. We can use any of the above methods for finding the square root, such as pr...
One square root is, from Eq. (3.44), 3eiπ/2=3eiπ/4. The other square root is, from Eq. (3.45), 3eiπ+π/4=3ei5π/4. If a complex number is represented as x+iy, it is easier to transform to polar coordinates before taking the square root of the number....
The properties of the square root are used to simplify equations, or in such a case, to help solve them so that if you have two terms separated by equality and the variable is squared, you can use one of the properties of the square root to un-square the variable. This procedure con...
