Main Question or Discussion Point

Hello,

I have come across this part of a question which has puzzled me.

Expand (x + y/sqrt[n] + z/n)^2
I assume it means Taylors, but could someone help me understand this?

Not Taylor's expansion, they just mean to multiply it out:

(x + y/sqrt[n] + z/n) * (x + y/sqrt[n] + z/n) = x2 + . . .​

Ah, typical of me. I always look for the hardest way of doing things.

Thank you!

Not a taylor series - just square the whole thing.

[tex]
\left(x + \frac y {\sqrt n} + \frac z n\right)^2 = \left(x + \frac y {\sqrt n} + \frac z n\right) \cdot \left(x + \frac y {\sqrt n} + \frac z n\right)
[/tex]
