I assume she wants acceleration as xxx +-yy
The rules are here: do the division first, then the square rooot (power is 1/2)

we'l find the time, t, for the ball to fall from the tabletop to the floor. use the equation Δy=viΔt+at^2/2. Take the vi to be zero and a to be 9.81 ±.02 m/s^2. you must first solve this equation for t.
Δy=.922m
what am i suppose to do with the acceleration because it has an uncertainty attached to it. do i have to come up with 2 answers? on the sheet the teacher gave me it only gave me on black spot to so there has to be one answer.
