What number is ixx?

Answer 1

Ah, isn't that a fun question? You see, the number "i" represents the square root of -1, so when you have ixx, it's like multiplying i by itself twice. This simplifies to -1, because i multiplied by i is -1. Just a happy little mathematical journey we went on there!

Answer 2

The number i is the imaginary unit, representing the square root of -1. When you square i, you get -1. So, i^2 = -1. Therefore, ixx would be equivalent to i^2 * x = -x, where x is any real number.

Answer 3

It is the Roman numeral for 19 but in today's notation it is XIX but the Romans themselves would have probably used IXX
