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.
