Thread: Complex Number System

So I'm having trouble with imaginary numbers...
here's the problem

Evaluate the following square root expression

√(-8x^9)

the ^ represents superscript so its x to the 9th power

this is my process so far

√(-8x^9)
= i√(8x^9)
= 2i√(2x^9)

I fully realize that you have posted in the pre-algebra/algebra forum.
That said, I have some real concerns with you question.

Many of us do not like the notation if is a complex number.

Now if is a real number, then there are additional problems.

For example: if then is a real number.

If then

All "bets" are off if is a complex number!
