a.

Given that nnn is a positive integer, express

52+3n−53n−2\frac{5}{2+3\sqrt{n}} - \frac{5}{3\sqrt{n}-2}2+3n​5​−3n​−25​

as a single fraction not involving surds.

b.

Hence, deduce that

52+3n−53n−2\frac{5}{2+3\sqrt{n}} - \frac{5}{3\sqrt{n}-2}2+3n​5​−3n​−25​

is a rational number for all positive integer values of nnn.
