The population of the united states is about 3.2x10^8 the population of the united states is about 80 times the population of oregon write the population of oregon in scientific notation

The answer to your question is:  4 x 10 ⁶ = population of Oregon

Step-by-step explanation:

Data

Population of the USA = 3.2 x 10⁸

Population of the USA = 80 population of Oregon

Process

                           3.2 x 10⁸  = 80 population of Oregon

                           3.2 x 10⁸ / 80 = population of Oregon

                          4 000 000 = population of Oregon

                           4 x 10 ⁶ = population of Oregon

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
