Q11. Two clasumatex Salma and Anil simplified two different expressions during the revision hour and explained to
cach other their simplification
Salma explain simplification by rationalizing the denominator and Anil explains simplifications of (vā + V3)
(123) by using the identity (a + b) (a-b). Answer the following questions
a
What is the conjugate of V5 + 3
I V5 + V3
II V5 - 13
V5 X V3
V3
IV.
VE
6. By rationalizing the denominator of Salma got the answer
11
VŽ (V5 - 7)
III
V5 - V3
VE (V5+1)
IV
2
identity to solve (15+ V) (15 - 15)
c. Anil applied
1 (a+b) (a+b)
II (a+b) (a-b)
III (a-b) (a-b)
IV (x + a) (x+b)
d (V2 + V3) (V2 - 73) =
1 - 1
