My solution to the problem is as follows: sqrt(294) - sqrt(24) + sqrt(54)  = sqrt(49 * 6) - sqrt(4 * 6) + sqrt(9 * 6)  = sqrt(49)*sqrt(6) - sqrt(4)*sqrt(6) + sqrt(9)*sqrt(6)  = 7*sqrt(6) - 2*sqrt(6) + 3*sqrt(6)  = (7 - 2 + 3)*sqrt(6)  = 8*sqrt(6)  = sqrt(64)*sqrt(6)  = sqrt(384) = 8*sqrt(6) Therefore, the answer is letter B, 8 square root of 6 I hope my answer has come to your help. God bless and have a nice day ahead!
