When you drop a 0.40 kg apple earth exerts a force on it that accelerates it at 9.8 m/s squared toward the earth. If the mass of the Earth is 5.98 times 10 to the 24th power, what is the magnitude of the earths acceleration.

a very good zero
= m g / M
where m and M are masses of apple and Earth, g=9.8 m/s^2
( in physics always mind the units of measurements)

Insignificantly small. Yes the Earth would technically be pulled toward the apple, but the amount of force due to gravity, about 4 N, would not accelerate an object as massive as the Earth very much. The acceleration of the Earth toward the apple is negliable enough to be ignored in virtually all applications.

there's a formula for that, look in your physics book
