Question

A probiotic colon health product contains, in each capsule, 3 billion viable cells of Lactobacillus acidophilus and

Bifidobacterium longum. Express, by exponential notation, the number of viable cells in a container of 30 capsules.

Answer 1

The number of viable cells in a container of 30 capsules is 9×10^{10}.

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
