2^4=16 means 2 is the 4th root of 16.
Similarly, 4^2=16 means 4 is the 2nd root of 16.

the nth root of a number is another number that when multiplied by itself (n - 1) times, gives the first number

so saying 2 is the 4th root of 16 means 2 multiplied by itself 3 times gives 16

that is, 2*2*2*2 = 16
