1/2√8-1/3√27+4√50
To fine the square root of a number, find two factors of it, one of which is a perfect square. Perferably the highest perfect square that is a factor of the number. So the square root of 8 would be sqrt%284%29%2Asqrt%282%29. You can simplify that two 2sqrt%282%29, since the square root of four is two. So substitute that and get 1%2F2%282sqrt%282%29%29-1%2F3%28sqrt%2827%29%29%2B4%28sqrt%2850%29%29. Then find the square root of 27. You should get 3sqrt%283%29. Then get the square root of 50. You should get 5sqrt%282%29. Then plug these in to the original equation. 1%2F2%282sqrt%282%29%29-1%2F3%283sqrt%283%29%29%2B4%285sqrt%282%29%29. Then multiply everything and get sqrt%282%29-sqrt%283%29%2B20sqrt%282%29. Combine like terms and get 21%28sqrt%282%29%29-sqrt%283%29.
