The sum of distinct prime factors of \(12^2\) |
The sum of distinct prime factors of \(50^3 \) |
\(12 = (2)(2)(3)\), which means \(12^2 = [(2)(2)(3)][(2)(2)(3)]\)
So, the sum of the distinct prime factors \(= 2 + 3 = 5\)
\(50 = (2)(5)(5)\), which means \(50^3 = [(2)(5)(5)][(2)(5)(5)][(2)(5)(5)]\)
So, the sum of the distinct prime factors \(= 2 + 5 = 7\)
Answer: B

Answer: B
This was my answer as well, however the the correct answer appears as "C"
Carcass, care to share the explanation on this one? Thanks
