Across the different colleges in Washington D. C. there is a population of approximately 3x10⁵ college students. Approximately how many college students are in Washington D. C.?

300,000

Step-by-step explanation:

3 x 10 to the 5th power, if you took 10 and multiplied by five to make 10 x 10 x 10 x 10 x 10, which would be 100,000. then multiply by the 3 and get 300,000

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
