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

Apologies the question is

100^2/100*100^3

Given answer was 10^-4?? How do we get this?
