    Equating two SI units of time

    If I have two numbers;

    434*10^15 and 1*10^301

    How do I get these into a format in which they have the same coefficient? I know it has something to do with laws of indices and log rules etc, but am still a bit confused.

    Thanks

    I think you are have to give us a bit more of a clue about what you really want. To do what you appear to be asking would involve over 2 hundred zeros somewhere. It seems implausible that you mean what you seem to be asking.

    Sorry I should have made myself clear. I would like to get them both into the format x*10^y where x is the same number in each. So for example;

    1*10^50 and 1*10^18

    You cannot get them in this format because one number starts with 4 and the other with 1. However, since 434 = 4.34\cdot10^2, we have 434\cdot10^{15}=4.34\cdot10^{17}.
