Simplify. 3/x5+1/14/x5
For this answer I got: x2/x9
Divide. x^249y^2/6x^2+42y/(x^27xy)
For this answer I got: (x+7y)/6x(x^2+7y)
Add. Express your answer in simplest for. x/6+3x/6
For this answer I got: 2x/3
Please check my answers. Thank you.

Assuming that you have no typos, deal with like terms first.
3/x  4/x = 1/x
1/1 = 1
5+15 = 9
This gives me 1/x 9

Unless the plus sign is supposed to be negative, you will not get 2x/3.
Because of apparent typos, I am not even going to deal with the division problem. However, I hope what I did helps. Thanks for asking.
