Can somebody please help me with this problem?

This is the index-„³ 5 6^-5

The radical sign did not show, but the problem is:

5 is the index (outside the radical sign and then 6 is squared to the -5th power (inside the radical sign is under the radical sign)

when adding and subtracting radical expressions does the doubled number go in the inner or outter of the radical
