Simply it as follows:
1 + 39 = 40
2 + 38 = 40 etc
18 + 22 = 40
19 + 21 = 40
There are 19 of these plus 40 itself . . .therefore 20 of them
20 x 40 = 800
And finally the last number not used, 20
Therefore 800 + 20 = 820

Step-by-step explanation:
This root can be rewritten as:



Since 6487209 is a multple of 3, the expression can be rearranged as follows:

2162403 is also a multiple of 3, then:


720801 is a multiple of 3, then:

240267 is a multiple of 3, then:


80089 is a multiple of 283, then:




Answer:
Unfortunately, we can't do anything with 41 as it has no factors. Since
is already simplified, try submitting that as your answer. If that doesn't work then try un-doing their steps and get rid of the 3:



Hope this helps!
