Question

Throughout his photography career, Paul has photographed 200 adult elephants in the wild. If each elephant weighed approximately 1.4 x 104 pounds, find the combined weight of all 200 elephants expressed in scientific notation.

Answer 1

`(200*1.4) *10^4`

And we got:

`280 x10^4`

And if we move the decimal point two units to the left we got:

`2.8 x10^6`

Explanation:

We know that each elefeant weight about
`1.4 x10^4`

And we have a total of 200 elephants so then we can find the total weights for the elephants with this formula:

`200 *1.4*10^4`

Using the properties of multiplication we can do this:

`(200*1.4) *10^4`

And we got:

`280 x10^4`

And if we move the decimal point two units to the left we got:

`2.8 x10^6`
