SOLUTION:
Step 1:
In this question, we are given the following:
[tex]\frac{8\text{ x 10}^5}{4\text{x 10}^{-1}}[/tex]Step 2:
The details of the solution are as follows:
[tex]\frac{8\text{ x 10}^5}{4\text{ x 10}^{-1}}=\frac{8}{4}\text{ x 10}^{5-\left(-1\right)}=\text{ 2 x 10}^{5+1}\text{ = 2 X 10}^6[/tex]CONCLUSION:
The final answer is:
[tex]2\text{ x 10}^6[/tex]
