1) You look for a common factor between the two numbers. Prime factorization can help here. 2) You divide both numbers by this factor. Three goes into both 21 and 33. 21 to 33 can be simplified to 7 to 11.
33/7 - 22/21 the least common denominator is 21 = (33 x 3)/(7 x 3) - 22/21 = 99/21 - 22/21 = 77/21 = (77 ÷ 7/(21 ÷ 7) = 11/3 =3 2/3
sqrt(48) =sqrt(16 x 3) = sqrt(16) x sqrt(3) =4 sqrt(3) =6.928 (rounded)
No.
sqrt(36/4)3 = sqrt(9)3 = 33 = 27
21 : 6factor out a 33(7 : 2)7 : 2==========simplified ratio
7 x sqrt(9) + 4 x sqrt(9) = 21 + 12 = 33
It is sqrt(33).

No.
Dist = |sqrt[(23 - 4)2 + (-33 - 9)2]| = |sqrt[192 + 422]| since -422 = +422 = |sqrt[361 + 1764]| = |sqrt[2125]| = 46.098 (to 3 dp)
Sqrt[(600-240)/(1145-56)] = Sqrt(576/1089) = sqrt(576)/sqrt(1089) = 26/33
sqrt(66) + 33 = 8.1240 + 33 (approx) = 41.1240 approx.
