Question

Frequency and wavelength problems. I get the correct number but not the correct exponent.

Answer 1

\[v=f*\lambda\] check whether eqn is right and use calculator.

Answer 2

One thing I find helps on problems like these is to make liberal use of the parentheses on my calculator. If you do not fully encompass the \[Number*10^x\] you will find that you end up with an incorrect value for the division problems.
