Question

during the first year of operation of company produce 4.3 x 10 to the 9th power reams of paper. During the second year the company produce 8.1 x 10^9 reams of paper. how many reams of paper were produced the first two years

Answer 1

Reams of paper produced:

First year: 4.3 x10^9

Second year: 8.1 x10^9

To find how many reams of paper were produced in the first two years, we need to add the quantities from both years:

`4.3*10^9+8.1*10^9`

Since both quantities have the term 10^9, we can factor it as follows:

`(4.3+8.1)*10^9`

Now we only add the numbers 4.3 and 8.1, the result of the sum is 12.4:

`12.4*10^9`

Answer: 12.4x10^9 reams of paper
