Eddie Halfpenny: How do I convert the sum 2.2 to a % using the formula x10^9/L if the range is (2.0 - 7.5) I am not familiar with mathematical equations such as this.
Our guest gave you a very good explanation of what the ^ (hat) means. (thank you guest - we need lots of helpers here)
Your actual question doesn't make much sense.
Is it a part of a bigger question?
