reducing to fundamental units

λ - m

γ - N.m

ρ - kg.m

The final answer is velocity, so m.s

If you multiply all three together [ie λ x γ x ρ] we have m x kg.s

Not quite what we wanted. We needed the kg to cancel out, so one of γ or ρ needed to be in the denominator.

The fact that all units were squared doesn't matter - we can throw in a √ at the end to fix that.

have a play round and see how you get on.
