Question

Evaluate. Express the answer in scientific notation

and decimal notation.
4x1010
5x1014

Answer 1

1.
`40000000000`
2.
`500000000000000`
(In case you were asking me to multiply, 20 × 10^24)

Explanation:

Given the following questions:

`4*10^(10)`

`5*10^(14)`

In order to find the answers, we take note on how the exponents are positive. We also need to remember how integers always have invisible decimal points.

Question one:


`4*10^(10)`

`4*10^(10) =4.0.0.0.0.0.0.0.0.0.0.`

`4.0.0.0.0.0.0.0.0.0.0.=40000000000`

`40000000000`

Question two:


`5*10^(14)`

`5*10^(14)=5.0.0.0.0.0.0.0.0.0.0.0.0.0.0.`

`5.0.0.0.0.0.0.0.0.0.0.0.0.0.0.=500000000000000`

`500000000000000`

In case you were asking me to multiply:


`40000000000*500000000000000=20000000000000000000000000`

`20000000000000000000000000=20*10^(24)`

`20*10^(24)`

Hope this helps.
