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.
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.
To express the population in scientific notation, we need to multiply the current population by 5 and consider the exponent for the number 10.
Given:
Current population = 2.6 × 10^16
To find the population in 30 years:
Population in 30 years = Current population × 5
We can calculate this using the given values:
Population in 30 years = 2.6 × 10^16 × 5
To multiply, we multiply the numerical parts and add the exponents:
Population in 30 years = 2.6 × 5 × 10^16
Multiplying 2.6 and 5 gives us:
Population in 30 years = 13 × 10^16
So, the population in 30 years is 1.3 × 10^17.
