31.2 meters to cm (2) 17,216ft to miles (3)express 2646 as a product of prime #'s using exponents?

Answer 1

1) 1m=100cm
31.2m=3120cm

2) 17216/5280 (there are 5280 ft in a mile)
=3.260606miles

3) 2*3^3*7^2 (2 times 3 cubed times 7 squared)

Answer 2

31.2 m * 100 cm/m = cm
17,216ft/ 5280 ft/mi = mi
2646 factored to smallest primes is hunt and peck; divide by 2 =1323 which is divisible by 3 =441, divisible by 3 again=147, divisible by 3 again =49 and 49 is 7^2 so 2646 = 2^1*3^3*7^2, Notice I started with the smallest prime # and worked my way up
