Can you simplify the following radicals

/ = square root symbol, NOT fraction.

(1) (7/5 + 6) (2/5 + 7/3)

(2) 7/7 + 5/20 - (9/28 + 6/5)

(3) 3^/24p6^n^9

(4) 3/369 + 4/44

No need to show work!

(7√5 + 6)(2√5 + 7√3)
14√25 + 49√15 + 12√5 + 42√3
70 + 49√15 + 12√5 + 42√3

7√7 + 5√20 - 9√28 + 6√5
7√7 + 10√5 - 18√7 + 6√5
16√5 - 11√7

³√(24p^6n^9)
2p^2n^3 * ³√3

3√369 + 4√44
9√41 + 8√11

My apologies, but I cannot simplify those radicals. Sorry!
