I don't understand exponents

You must apply the law of exponets.

You must apply only at the same letter. X or Y

$\frac{x^{m}}{x^{n}} = x^{m-n}
$

$\frac{x^{3}}{x^{6}} = x^{3-6} =x^{-3}$

$\frac{y^{3}}{y^{-6}} = y^{(3-(-6))} =y^{3+6}=y^{9}$

$\frac{20x^{3}y^{3}}{32x^{6}y^{-6}} = \frac{20x^{(3-6)}y^{(3-(-6))}}{32}=\frac{20x^{(-3)}y^{(3+6)}}{32}=\frac{20x^{(-3)}y^{(9)}}{32}
$

But
$x^{-n} = \frac{1}{x^{n}}$
Then

$\frac{20x^{3}y^{3}}{32x^{6}y^{-6}} = \frac{20x^{(-3)}y^{(9)}}{32}=\frac{20y^{9}}{32x^{3}}=\frac{10y^{9}}{16x^{3}}=\frac{5y^{9}}{8x^{3}}$

Jason begins at the start of a path and rides his bike 11 and a half miles on the path the path is 12 and a 1/4 miles long whats

Paladinen [302]

We just need to subtract the total miles he has already rode from the total miles of the path.
12.25-11.5
0.75
So, he must bike 3/4 miles to reach the end.
