We have the following expression:
3 ^ root (128a ^ 13b ^ 6)
Rewriting we have:
3 ^ root ((64 * 2) * ((a ^ 12) * (a)) * ((b ^ 3) * (b ^ 3)))
3 ^ root (((4 ^ 3) * 2) * ((a ^ 12) * (a)) * ((b ^ 3) * (b ^ 3)))
((4) * (a ^ 4) * (b ^ 2)) * 3 ^ root ((2) * (a))
Answer:
((4) * (a ^ 4) * (b ^ 2)) * 3 ^ root ((2) * (a))
option 2
