Question

In the year 2000, the United States had about 100,300,000 people registered to use cellular phones. How would this number of people be written in scientific notation?

Answer 1

Answer:

1.003 * 10^8

Step-by-step explanation:

Given that :

The United States has about 100,300,000 registered to use cellular phones in the year 2000

100,300,000 in scientific notation:

(100,000,000) + (300,000)

(1 * 10^8) + (3 * 10^5)

To ensure equal power :

300,000 = 3 * 10^5 = 0.003 * 10^8

Hence,

(1 * 10^8) + (0.003 * 10^8)

(1 + 0.003) * 10^8

1.003 * 10^8
