Answer:
5:4
Step-by-step explanation:
If point B divides the segment AC in the ratio 2:1, then
AB=2x units and BC=x units.
If point D divides the segment AB in the ratio 3:2, then
AD=3y units and DB=2y units.
Since AD+DB=AB, then

Now,

So,

R=50 because 8×50=400 so that is what r would equal
The exponent would be 5 the fifth power, because since the number your using to multiply it by is 5 and you are multiplying is by 5 fives it would be 5 to the fifth power
