Problema Solution
How can you express (15 + 30) as a multiple of a sum of whole numbers with no common factor?
Answer provided by our tutors
The sum of 15+30 = 45 and can be expressed as a multiple of prime factors:
(3^2)5
So (15+30) could be expressed as 9*5, but it can not be expressed as a non-repeating multiple of prime factors.
