made was in Chicago in 1998. It weighed a whopping 1.23 x 10^5 pounds. How
much more did the pizza weigh than the bowl of mashed potatoes?
(I need an answer by today please and thank you) ​

Answer 1

We have been given that the biggest bowl of mashed potatoes ever made weighed
`4.5* 10^4` pounds and was created at the Iowo State Fair in 2005. The biggest deep dish pizza ever made was in Chicago in 1998. It weighed a whopping
`1.23* 10^5` pounds.

To find how much pizza weighs more than bowl of mashed potatoes, we will subtract weight of mashed potatoes from weight of pizza.

`1.23* 10^5-4.56* 10^4`

`1.23* 100000-4.56* 10000`

`123000-45600=77400`

Now we will convert
`77400` into scientific notation as:

`77400=7.74* 10^4`

Therefore, the pizza weighs
`77400=7.74* 10^4` pounds more than the bowl of mashed potatoes.
