Final answer:
The values of m in the equation m^2=16 are 4 and -4.
Step-by-step explanation:
To determine the values of m in the equation m^2 = 16, you need to take the square root of both sides of the equation. The square root of 16 is 4, so the equation becomes m = ±4. Therefore, the values of m are 4 and -4.
