Hi. I have recently scratched the basics of complex numbers and just learned the modulus. I looked at one of the examples on my textbook which states that
l (-1+ 31/2i)l = ((-1)2+(30.5)2)1/2
But according to my understanding, isn't the l31/2il supposed to be sqrt of 3i2, in which it is a 3(-1). But typing the equation into my graphic calcuator reveals the results as shown on the textbook, meaning my understanding is wrong.
Any helps please? Thanks.
