The 0th power of zero is 1. ✓-1 (square root of -1) does not exist. In maths and physics i is defined as the square root of -1. Any number with i as part of it is a complex number.

Ok here's another easy question:

Square root of -1?

Hi Lisa,
i squared = -1.

so the answer is i which is called an imaginary number
but in fact is vital to get the correct results in maths.
That's all about complex numbers -
a very important part of maths.

What is the most beautiful expression in maths?
Euler’s formula -
It simplifies very complicated maths and is
essential in engineering and science.
It's one of the first things you learn in maths at Uni
and continues to be used all the way through any maths course.

Do you want my next topic -
the fundamental theorem of arithmetic?
It involves prime numbers.

then

The fundamental theorem of algebra?

then

the fundamental theorem of calculus?
