Answer: 
4 × 10^0 kg or 4×E0 kg.
Explanation:
Before delving into or solving the Calculation, let us check one or two things about worker bees. 
WHAT IS A WORKER BEE?. 
Bees generally are social insects living in an organized community and they consist of three castes which include; the drone bees, worker bees, and the queen bees. 
The queen bees are the female bees while the drone bees are the male bees.
The WORKER BEES are female bees too, but the only difference between them and the queen bees is that they (worker bees) do not reproduce like the queen bees. They are saddled with the responsibility of looking for food and maintaining the hive temperature.
Now to the question, the mass of a bee= 1 × 10^-4 kg. And there are 4 × 10^4 bees in hive. Therefore, the mass of all the worker bees in the hive together = (1 × 10^-4) × (4×10^4). 
==> 4 × 10^0 kg, or 4E0 kg.
