The rationalizing factor of binomial surd is also called Conjugate of binomial surd
180 = 2x x 3y x 5. The value of x and y is 2
The product of √ and √ is ab ab √
In two triangles ‘b’ if their corresponding sides are proportional they they are called Similar
If ‘a’ and ‘b’ are any two positive intetgers if H is HCF of (a,b) and L is LCM of (a,b)
Then the relation between them is expressed as a x b = H x L.

(7 x 11 x 13 + 13) is a composite number. Justify the statement.
Ans:
(7 x 11 x 13) + 13
= 13 [(7 x 11) + 1]
= 13 [77 + 1]
= 13 x 78

√81 = √273 = 3 √3
+
+
+
√128 = √64 2 = 4 √3

20. Simplify 3x √ + 3√ - 2√9 Ans : 3x √ + 3√ - 2√9 = 3x √x + 3√x x x = 2√9 x x x x
=3x √ + 3 √ − 2 3 x √
= 3x √ + 3 √ − 6 √
= 6x √ - 6x √
=0
21.
Ans:
Find the sum of (√12 + √20), (3√3 + 2√5) (√45 − √90)
(√12 + √20) + 53√3 + 2√56 + (√45 − √90)
= 5√4 3 + √4 56 + 53√3 + 2√56 + (√9 5 − √9 10)
= (2√3 + 2√5) + (3√3 + 2√5) + (3√5 − 3√10)
= (2 + 3) √5 + (2 + 2 + 3) √5 - 3√10
= 5√3 + 7√5 − 3√10
