Express 80 as a product of it's prime factors using index notation

I can't help you with index notation, but i can give you the other part.

80 = 5 X 16 = 5 X

5 and 2 are prime numbers.

I picked five because 80 is not divisible by 3.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
