-- Posted by KRNsoccerplayer24 at 10:26 pm on Dec. 7, 2008 8/squareoot 2.....it says to ratinalize the denominator and simplify....would i just multily it by squareroot 2 and it would be 8 squareoot 2? -- Posted by Sector Corrupt 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) -- Posted by lucid dreams19 at 10:28 pm on Dec. 7, 2008 youve got the right idea but the answer would be 8squareroot2/2 -- Posted by blufindr at 10:28 pm on Dec. 7, 2008 Uh. 8 = 2*2^(1/2) Therefore, it's just 2. -- Posted by matto at 10:29 pm on Dec. 7, 2008 8 sqrt(2) / 2 = 4 sqrt(2)
