In a clinical research, a special type of cancer cells affecting the skin was discovered. The growth occurs by the division of cells. A cell divides 5 times in an hour. So, in 6 hours, the cell will divide 5 • 5 • 5 • 5 • 5 • 5 times.

in 6 hours, the cell will divide

5 • 5 • 5 • 5 • 5 • 5 times

• 5 x 5 x 5 x 5 x 5 x 5

• = 15, 625

Base- the larger number at the bottom

Exponent-the smaller number on top
