Question

A single tree produces about 2.6 × 10² pounds of oxygen each year. The Amazon rainforest has about 3.9×10^11 trees.

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

Enter your answer by filling in the box.

$___ pounds per day

Answer 1

Answer:

There are about  $1.014$ × $10^{13}$ pounds of oxygen produced in the Amazon rainforest per day.

Step-by-step explanation:

Since we want to find how much oxygen is produced in a rainforest with thousands of trees, we would have to multiply.

Multiply 3.9 and 2.6 to get 10.14.  When multiplying exponents of the same base, you add the exponents. So you should get $10^{12}$. The equation should look like this: $10.14$ × $10^{12}$

This equation is not complete for as the "10.14" should only have a single-digit less than 10. Therefore, we should move the decimal point over one place to the left and as we do that, increase the exponent number by one. Now our final equation should look like this: $1.014$ × $10^{13}$
