It just equals 5 * (sqrt(13)+3). Remember -- you only need to remove the radical from the denominator, not the numerator.
I'm not sure how you got 13-3, but it's incorrect.
Denominator = (sqrt(13)-3) * (sqrt(13)+3)
= (sqrt(13) * sqrt(13) + 3*sqrt(13) - 3*sqrt(13) - 9)
= 13 - 9 = 4 So the answer would be: 5/4*(sqrt(13) + 3)
(As an aside, and with all due respect, if you have any desire to continue your education in math or the sciences, or if you ever want to get serious about sports betting, I'd have to suggest taking some time to brush up on your elementary algebra.) |
Well thank you...
As a side note, I am not bad at Math, just have not dealt with Radicals in a long time. Once I got passed these I wont have to deal with them again. To put it mildly, Radicals have never been my friend anyway.
