This worksheet is about the division of algebraic terms with powers.
Remember what 10a2b5 and 15a3b2 mean and divide them by subtracting the relevant indices.
|15 x a x
Cancel down a matching number of a terms from the top of the fraction with a terms from the bottom. Similarly with b terms.
This leaves us:
|10 x b x b x b
|15 x a|
which reduces by dividing top and bottom by 5 to
