Which 2 ways can you represent 16 in powers?

Answer 1

16 = (256)1/2

Also, 16 = (64)2/3 .

There are an infinite number of 'correct' answers to this question as it is posed.

To limit the number of good answers to 3, insert 'integral' before 'powers'.

To limit to 2 only, you need to disqualify (16)1 . Yes, this is picky-picky,

but mathematics is all about precision and absolute certainty.

16 = (2)4

16 = (4)2

Answer 2

16 = (2)4

16 = (4)2
