Question

The population of a country in 1950 was

Answer 1

Answer:

$1.86*10^{10}$

Step-by-step explanation:

We need to multiply the 1950 population by the number given (3*10^2)

So, we have $(6.2*10^7)*(3*10^2)$

we will multiply the constants in front and add the exponents of 10 together and write:

$(6.2*10^7)*(3*10^2)\\=(6.2*3)*10^{7+2}\\=18.6*10^9$

This in standard form is 1.86 * 10 ^ 10
