I thought I had this in good understanding but I've had my legs kicked from under me on this example. An expression such as;
[MATH]{3}{p}{q}-{2}+5{p^2}[/MATH] has one constant term, namely [MATH]-{2}[/MATH]
The book does not mention square roots in the discussion but asked the question, identify the constant terms in;
[MATH]{2x}+{5}\sqrt{2}+{x^2}[/MATH]
So I answered the expression by writing [MATH]{5}[/MATH] which I clearly got wrong!
So the [MATH]\sqrt{2}[/MATH] is that then multiplied by [MATH]{5}={7.1}[/MATH] but written as [MATH]{5}\sqrt{2}[/MATH] as the answer.
All I'm asking is, should a constant term in conjunction with a square root be thought of as being the constant term and written as [MATH]{5}\sqrt{2}[/MATH]
