some algebra help (radicals)

I hope I am writing this down right.. I am trying to do some practice questions to learn

10^5 (sqrt)2y - 4^5 (sqrt)2y

I am trying to figure out how to solve this

They gave us some answers to choose from, but I am clueless on how to solve this

6y ^5 (sqrt)2

6y ^5 (sqrt)2y

- 6y ^5 (sqrt)2y

- 14 ^5 (sqrt)2y

14 ^5 (sqrt)2y

The answer is (10^5 - 4^5) sqrt (2y). This does not agree with any of your choices. Are you sure you copied the problem correctly?

hmmm let me look

I think I did.. It is really hard to put the symbols here.
