What if we divide  x^5  by  x^2  ?

x^5 / x^2

There is a rule for this, but, it's way better to understand what's going on than to just try to crunch the rule.

Let's write out what each one means:

x^5 / x^2 explained

Remember that   x / x = 1 ...  Just like   3 / 3 = 1 ...

So, we can cancel some 1's:

x^5 / x^2 = x^3


TRY IT:

Simplify   y^8 / y^3  by writing out what each one means:
