25 should be 3 square roots of 8, 4 square roots of 2, and then the square root of 50. 26 should be all those multiplyed together. First you need to reduce so, the square root of 28 will be 2 square roots of seven because you can pull out two twos. then the square root of 112 would be 4 square roots of seven. so when you multiply both of the 2 square roots of seven you get 28. so the rest is
28 x 2 x 3 x 4 square roots of 7. you cannot reduce the square anymore so the answer will be 672 square roots of 7. (28 x 2 x 3 x 4= 672)
