Question

A large oak tree has 2 × 10 ^ 5 Leaves during its lifespan a large forest can have About 5 × 10 ^ 3 oak trees approximately how many leaves grow on large oak trees in a forest during the lifespan of the trees

Answer 1

1,000,000,000 leaves or 1 x 10^9 leaves

Explanation:

One large oak tree has 2 x 10^5 leaves, so we can make that number to 200000

There are 5 x 10^3 oak trees in a forest, we can make that number to 5000

Since we want to find out how many leaves are in the whole forest we multiply: 200000 x 5000 = 1,000,000,000

So approximately there are 1 billion leaves or 1 x 10^9 leaves
