3 to the 9th power over 3 to the 2nd power =

Answer:

When you divide you take away the indices. 3^9÷3^2 = 3^9-2 = 3^7 For example imagine:
3x3x3x3x3x3x3x3x3 = 19683
divided by
3x3 = 9
= 2187

Or you can cancel out all the numbers e.g. because there are two at the bottom and 9 at the tpo you can cross out the two at the bottom. But if you cross out two at the bottom you also have to cross out to from the top leaving you with 7. And then there will be 7 lots of three which leaves you with 3^7 = your answer
