# Surds watch

1. I am currently doing a past paper and I am stuck on this question:
2(5) x 2(4) x 2(2) It says to write this expression as a power of 2. How do I do it?
The numbers in brackets are powers.

I can do that bit, I just can't convert 211 into a surd :/

Why are you seeking to express things in surd form? Do you even know what a surd is?

Peace.
