As you've been so helpful to me before I wonder if you can give me a *hint* 
re the *approach* to the following problem.

I don't want to be given a solution nor an answer, but some hints about how 
to *go about* solving it.

I know the binomial theorem but find difficulty in applying it to this 
problem:

If Q = R^4 / Vx L

Using the Binomial theorem, find the percentage change in Q caused by a:

3% Decrease in L
2% Increase in R
4% increase in V

Any hints, tips but NO answers please :-)

TIA
