Answer:
The number of viable cells in a container of 30 capsules is 9×10^{10}.
Step-by-step explanation:
The number of viable cells of one capsule expressed in exponential notation is 3×10^{9} cells
In 30 capsules, we would have 30 times 3×10^{9} viable cells.
That is 30×(3×10^{9}) = 90×10^{9} = 9×10^{10} viable cells
