Question

express the following in the form of a+ib.a,b belongs to R .state the value of a and b.8.(1+i)^-³

Answer 1

Answer:

If z = a + ib is the complex number, then a and b are called real and imaginary ... 5.1.5 Addition of complex numbers satisfies the following properties ... then z = r (cosθ + isinθ) is called the polar form of the complex number, where ... Solution (1 + i)6 = {(1 + i)2}3 = (1 + i2 + 2i)3 = (1 – 1 + 2i)3 = 8 i3 = – 8i.Step-by-step explanation:
