Question

A single tree produces about 2.6 × 102 lb of oxygen each year. The Amazon rainforest has about 3.9 × 1011 trees.

About how many pounds of oxygen are produced in the rainforest each day ?

2.8 * 10^ ?

Answer 1

answer is ^11 i just took the test

Answer 2

To find result we have to mulitply oxygen produced by each day (by dividing
`2.6*10^2`by 12) by tree by number of trees.,
so we have
2.6*102:12=21.6- single tree/day

`21.6*3.9*10^11=8.45*10^12` (to the power of 12) - its our result.
