if x = 54 and y = 126, calculate the value of x / √y in its simplest form

Answer 1

x/sqry = 54/sqr126 = 54/3sqr14 = 18/sqr14

generally it's considered a "simplification" to eliminate the radical from the denominator, so multiply numerator and denominator by sqr14 to get

18sqr14/14 = 9sqr14/7 or (9/7)sqr14
