Step-by-step explanation:
I HOPE THIS HELPS ^^!!
We have been given an expression
. We are asked to find the solution to our given expression expressed as scientific notation.
Let us simplify our given expression.
Using exponent property
, we will get:
![8.5\times 2\times 10^3\times 10^5](https://tex.z-dn.net/?f=8.5%5Ctimes%202%5Ctimes%2010%5E3%5Ctimes%2010%5E5)
![17\times 10^{3+5}](https://tex.z-dn.net/?f=17%5Ctimes%2010%5E%7B3%2B5%7D)
![17\times 10^{8}](https://tex.z-dn.net/?f=17%5Ctimes%2010%5E%7B8%7D)
Now to write our answer in scientific notation, we need our 1st multiple between 1 and 10. So we will rewrite our expression as:
![1.7\times 10\times 10^{8}](https://tex.z-dn.net/?f=1.7%5Ctimes%2010%5Ctimes%2010%5E%7B8%7D)
![1.7\times 10^{1+8}](https://tex.z-dn.net/?f=1.7%5Ctimes%2010%5E%7B1%2B8%7D)
![1.7\times 10^{9}](https://tex.z-dn.net/?f=1.7%5Ctimes%2010%5E%7B9%7D)
Therefore, our required solution would be
.
