So, I'm really bad at math, I was wondering if you guys could help me out with this question...
18 r s to the 0'th power t to 9th power over.
6 r to the 8th s to seventh and t to the fourth.
$$\\\dfrac{18rs^0t^9 }{ 6r^8s^7t^4}\\\\ =\dfrac{3rt^9 }{ r^8s^7t^4}\\\\ =\dfrac{3t^{9-4} }{ r^{8-1}s^7}\\\\ =\dfrac{3t^{5} }{ r^{7}s^7}\\\\$$
its o and it is easy took me about 3 seconds
