7 7 7 7
(ii) 1
7 - 6
Multiplying the numerator and denominator by
( 7 + 6 ) we have
1 = 7 + 6
7 - 6 ( 7− 6)( 7+ 6)
= 7 + 6 = 7 + 6
7 − 6
(iii) 1
5 + 2
Multiplying the numerator and denominator by
( 5 - 2 ) we have
1 = 5 − 2
5 + 2 ( 5+ 2)( 5− 2)
= 5− 2= 5− 2
5−23
(iv) 1
7 - 2
Multiplying the numerator and denominator by
( 7+2) we have
