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.
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.
