Did you intend three variables?

(2/(a)^1/2).(x+a)^3/2 = (x+a)^1/2 leads to x = a  (a^(1/2))/2.

I don't think you fully understood my question. I would like to solve (2/(a^1/2)).(x+a)^3/2 to get (x+a)^1/2

Well then, ask your question properly. You should be asking WHEN does (2/(a^1/2)).(x+a)^3/2 = (x+a)^1/2 And that happens when a = x Would be nice if you used * for multiplication and bracket powers, like a^(1/2); a^1/2 means a divided by 2.

Thanks skipjack apologies for not realising that you had indeed answered the question I posed. I will try to create more accurate posts the next time. Thanks also sorban for explaining the error of my ways. Thanks Denis for highlighting that I could have posed my question better.
