The world population of a certain species is evaluated at 2.6 × 1016. By some projections, this population will be 5 times more important in 30 years. Express the population at that time in scientific notation.

1 answer

To express the population at that time in scientific notation, we can multiply the current population by 5 and represent it with the appropriate exponent.

Population in 30 years = 2.6 × 10^16 * 5

= 13 × 10^16

= 1.3 × 10^(16+1)

= 1.3 × 10^17

Therefore, the population at that time will be 1.3 × 10^17.
