To simplify the square root of ±sqrt(16/49), follow these steps:

- Simplify the expression inside the square root, if possible.
- Take the square root of the simplified expression.
- If the expression is positive, the simplified square root will be the positive square root of the simplified expression. If the expression is negative, the simplified square root will be the negative square root of the simplified expression.

For ±sqrt(16/49):

- Simplify 16/49: 16/49 = (4^2) / (7^2) = (4/7)^2
- Take the square root of (4/7)^2: ±sqrt((4/7)^2) = ±(4/7)
- Since the expression is positive (no negative sign in front of the square root), the simplified square root is: ±(4/7)
