Thank you for your reply.

It basicly says calculate, nothing more.

1/ (4th root of 2 + 4th root of 4 + 4th root of 8 + 2 )

And the answer is 1- 1/ 4th root of 2

Inside the bracket is a 'geometric series'. Do you know how to find the sum of a geometric series like the following one?

Hopefully you can complete the question.
