9 = 9(9-V15 ) = 9(9 - V15 ) ==> 9(9-V15)
9+V15 (9+V15)(9 -V15) 81 - 15 66
b)13/(1-V7)=
13 = 13(1+V7 ) = 13(1+ V7 ) ==> - 13(1+V7)
1-V7 (1+V7)(1-V7) 1 - 7 6
c)V3/(V8-4)=
d)8/(10+V3)=
8 = 8(10-V3 ) = 8(10-V3 ) ==> 8(10-V3)
10+V3 (10+V3)(10-V3) 100 - 3 97
e)6/(5V22)=
6 = 6V22 ==> 6V22 ==> 3V22
5V22 5V22.V22 5.22 55
f)1/(V10+V6)=
1 = 1(V10-V6 ) = (V10-V6 ) ==> (V10-V6)
V10+V6 (V10+V6)(V10-V6) 10- 6 4
g)4/(V15)=
4 = 4V15 = 4V15
V15 V15.V15 15
h)9/(V6)=
9V6 ==> 9V6
V6.V6 6
