Not sure if you meant like this,
3x%5E5%2A2x%5E3=3%2A2x%5E%285%2B3%29=6x%5E8
or like this,
%283x%29%5E5%2A%282x%29%5E3=3%5E5%2A2%5E3x%5E%285%2B3%29=243%2A8x%5E5=1944x%5E8

X-intercept, set y=0 and solve for x.2%280%29-4x-16=0
Y-intercept, set x=0 and solve for y.2x-4%280%29-16=0

(3x^5)(2x^3)=6x^8
----------------
2y-4x-16=0
2y=4x+16
y=2x+8
y int=8
(0,8)
x int=-4
(-4,0)
