Answer:
The simplified form is 
Step-by-step explanation:
To simplify the expression given to use, we need to reduce the given expression in its simplest form. There should not be any possibility for the further cancelling out of the division terms, if any.
Now the expression that is given to us is:

Here we will simplify it, as follows:

So this is the required simplified form.
Answer:
n=3.5
Step-by-step explanation:
2²=4

3.5×4=14
3.5×2²=14
8 * 684 = 5472
it is in between 5471 and 5473
