Hi there! Thank you for the opportunity to help you with your question!

1. 7^2 y^(8/3) y^(-2/3)/y^(7/3) = 49 y^(8/3-2/3-7/3) = 49 y^(-1/3)

2. 16^(-1/2) = 1/square root (16) = 1/4

3.  (16/81) ^3/4 = 16^(3/4) / 81^(3/4) = 8/27


Please let me know if you need any clarification. Always glad to help!
