Find a complex number w such that w90 −1

WebWhen multiplying a number by its conjugate you should end up with a real number. You can check which 2 complex numbers, multiplied, give you a real number. Let's start with your school's answer. If you do (7-5i)* (-7+5i), you get 49 +70i-25i^2. This, in simplified form, is equal to 74+70i, which is a complex number, not a real number. WebAug 2, 2024 · R e ( z + w) = R e ( z) + R e ( w) for any complex z, w. I m ( z + w) = I m ( z) + I m ( w) for any complex z, w. Write it as z = 8 + 4 i − z , then taking conjugates on both sides gives z ¯ = 8 − 4 i − z , and multiplying the two: Then z = 8 + 4 i − z = 3 + 4 i.

To solve such complex numbers, we have to know the value of i, which we can conclude from the expression, i2 = -1. If we take the square root on both sides, we get, √ i2 = √-1. Or i = √-1. Therefore, the value if ‘ i’ is √-1, which we cannot define, therefore, it is called an imaginary number. distance from mafikeng to welkom https://oalbany.net
