Question 1041213
(2√7+6√2)(√7+4√2) 
----
Distribute the 1st parenthesis::
(2sqrt(7)+7Sqrt(2)(sqrt(7)) + (2sqrt(7)+6sqrt(2))(4sqrt(2)
----------------------
Distribute in each of the two terms to get:
= 2*7 + 7sqrt(14) + 8sqrt(14) + 24*2
------------
= 14 + 48 + 15sqrt(14)
========
= 62 + 15*sqrt(14)
