√129+√216+√68+√169

First, do all the square roots, because that falls into exponents. 

sqrt(129) = 11.3578166916005472, or 11.35approximately.

sqrt(216) = 14.6969384566990686, Or 14.69 approximately.

sqrt(68) = 8.2462112512353211, or 8.24 approximately.

sqrt(169) = 13

The answer is this:13+11.35+14.69+8.24 ≈ 47.28 . :)

Thanks, rarinstraw.....if we just wanted to leave it in radical form, we would have....

√129+√216+√68+√169  =

√(43 * 3) +√(36 * 6) +√4 * 17) +√(13*13)   =

√129  + 6√6  + 2√17  + 13

Not really sure if it's much of an improvement.......!!!!!
