Simplify a complex number
WebbComplex numbers have the form a + bi, where a and b are real numbers and i is the square root of −1. All real numbers can be written as complex numbers by setting b = 0. Imaginary numbers have the form bi and can also be written as complex numbers by setting a = 0. Square roots of negative numbers can be simplified using WebbSince complex numbers have an imaginary part which we cannot divide into other numbers we rewrite the expression by multiplying by i or the conjugate on the denominator or …
