# Math Help - calculating into scientific notation

1. ## calculating into scientific notation

Calculate the following numbers into scientific notation (include units), for example 3.67 x10-6 m

(65 x104 m) x (4.5 x10-6s-1) = 2.925 x 10^-2 m/s

Are we using significance arithmetic? You seem to be rather careless about how you ask the question, anyway maybe what you mean is this

$(6.5\cdot10^4\ \text{m})(4.5\cdot10^{-6}\ \text{s}^{-1})=2.9\cdot10^{-1}\ \text{m/s}$
