WebMar 18, 2024 · We have: (2z +2i)4 = z4. ∴ ((2z + 2i)2)2 − (z2)2 = 0. Which is the difference of two squares; and so we use: A2 − B2 ≡ (A+ B)(A− B) to give: ((2z + 2i)2 − z2)((2z +2i)2 +z2) = 0. The first factor is again the difference of two square and using i2 = − 1, we can transform the second factor into the same: ((2z + 2i)2 − z2)((2z +2i ...

WebA complex number is the sum of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z. Here both a and b are real numbers. The value 'a' is called the real part which is denoted by Re (z), and 'b' is called the imaginary part Im (z). Also, ib is called an imaginary number.

WebThis is an interesting question. The real numbers are a subset of the complex numbers, so zero is by definition a complex number ( and a real number, of course; just as a fraction is a rational number and a real number). If we define a pure real number as a complex number whose imaginary component is 0i, then 0 is a pure real number. WebHow do you solve −48z2 = 3 ?
