What is the root of 16?

  1. 1

  2. 2

  3. 4

  4. 8

The correct answer is: 8

This is because 16 can be expressed as 2^4, and the root of a number is the number that when multiplied by itself a certain number of times, equals the original number. In this case, 4 multiplied by itself 4 times is equal to 16. The other options are incorrect because 1 multiplied by itself any number of times does not equal 16, 2 multiplied by itself any number of times does not equal 16, and 4 multiplied by itself 2 times is only equal to 16, not 4 times.
