    Dividing powers question

    Hi everyone

    im new to the forum.

    I have a problem that is 100^2/(100*100^2). The answer provided was 10^-4. I understand that when you divide by powers you subtract the powers from each other. But giver that I got 100^-2, I'm missing something simple. Can anyone help?

    I'm using * for times and ^ for to the power of.

    Grateful for any help

    thanks nmewin
