If x is an integer such that x^2 = 64, what is the value of x?

  1. 16

  2. 8

  3. -16

  4. -8

The correct answer is: 16

When solving for x in this equation, it is important to remember that the square of a negative number is a positive number. In this case, -8 and -16 are incorrect choices because their squares would result in positive numbers other than 64. Additionally, 8 is not a valid choice because it does not have a negative counterpart that, when squared, would result in 64. Therefore, the only option remaining is 16, which when squared would equal 64.
