**Question**

**Introduction**

This is a question
on indices (taught in secondary 2 or 3) that looks daunting. There is a way to unravel it. Look at the equation carefully. Can you see anything that looks like it is
repeated? What about that small little “+1”? How do you deal with it?

**Reminders and Tips**

**Solution**

**Summary**

The key to
solving this question is to apply the laws of indices and recognising repeated
chunks. This allows one to see the
overall structure of the expression and this often leads to a simplification of
the expression involved. It is good to recognise
the powers of small prime numbers. Like
atoms, prime numbers are the building blocks of all whole numbers. Using prime bases allows us to compare indices
more easily.
