Hi, I have a friend that is new to the U.S country and he is confused on a math formula he asked this: What does the symbol before N mean Lifetime risk of hemorrhage = 1 - (risk of no hemorrhage) ^ N

my response in my opinion I think the symbol before N means to the power of. I ask here to make sure if my thought is correct.

I want to give him the correct response. So I ask here to make sure. I would think the symbol means to the power of N.

Would I be correct?

ok, thanks this is what I thought. Does anyone have any good resources for me to review some math?

I be taking a placement exam soon and need to find some good resources to refresh my memory otherwise I be taking math classes that I already took a few years ago.

By the sound of things, you want to look at some precalculus.

It could denote the exterior product, sometimes called a wedge product, of two vectors, resulting in a bisector; however, this would seem too abstract for a college placement exam.
