Further indices - adding

Adding - $x^3y^3$

To remember this try simple numbers you know first

$10^2times10^2$

$=10times10times10times10$

$=10,000$

Now try $x^3y^3$

There is nothing to remember if you break this down.

$x^3y^3=x\timesx\timesx\timesy\timesy\timesy$

You can put these in a different order

$x^3y^3=xy\timesxy\timesxy$

Which can then be written as:

$x^3y^3=(xy)^3$

NOTE:

If it is $x^3y^2$

Which equals $x\timesx\timesx\timesy\timesy$

There is an odd $x$ so the above can’t be achieved.
