So this caution were asked to compute brew David over 50. We're gonna rewrite. This is Rudy over route 50 which is equal to the square root the two times for over the square root of two times 25 and this can be written us root too times. And then the spirit of four. The square before we're just gonna put us too. And then root two times. And then this would be really 25. But that's also a perfect square of just five. We can cancel these root twos, so we get our final answer of 2/5.
