\[\sqrt{15}-\sqrt{15*45}\] just multiply the things inside the root and there you go!
sqr root of 15 is 3.8729833462074168851792653997824 (feel free to shorten that :)) and the square root of 45 is 6.7082039324993690892275210061938 (again, feel free to shorten)
So what exactly is the answer?
well, we kind of gave you everything you need to know. get out your calculator!
