Replies matto Posted at 10:29 pm on Dec. 7, 2008 8 sqrt(2) / 2 = 4 sqrt(2) blufindr Posted at 10:28 pm on Dec. 7, 2008 Uh. 8 = 2*2^(1/2) Therefore, it's just 2. lucid dreams19 Posted at 10:28 pm on Dec. 7, 2008 youve got the right idea but the answer would be 8squareroot2/2 Sector Corrupt Posted at 10:28 pm on Dec. 7, 2008 Multiply the top and bottom by square rt 2. so it's 8/rt(2) * rt(2)/rt(2) = 8rt(2)/2 = 4rt(2) All 4 previous replies displayed.
