No they mean "indices" as in "raised to a power". The question should

read:

"Using the rules of indices, simplify the following and give your answers

with positive indices where applicable. Show your working clearly.

i) $\displaystyle \frac{3^{-2}.5^{-3}.20}{3^{-3}.5^{-2}.2}$

Also calculate $\displaystyle log_{11}(95)$ without using a calculator."

At least that's my guess at how the question should read.
