A.
= 3/√5
= 3/√5 × √5/√5
= 3 × √5 / √5 × √5
= 3√5/5
B.
= 26/2√13
= 13/√13
= 13/√13 × √13/√13
= 13 × √13 / √13 × √13
= 13√13/13
= √13
C.
= 7/√p – 3
= 7/√p – 3 × √p – 3/√p – 3
= 7√p – 3 / p – 3
D.
= √7/3
= √7/√3
= √7/√3 × √3/√3
= √7 × 3/3
= √21/3
a. 3/√5 = 3/√5 × √5/√5 = 3√5/5 =
b. 26/2√13 = 26/2√13 × √13/√13 = 26√13/26 = √13
