## Simplification

#### Simplification

1.  13 is equal to 48

1. Check through options

 = 1 + 1 3 + 1 (9 + 4/9)

 = 1 3 + 9 13

 = 1 39 + 9 13

 = 13 48

##### Correct Option: D

Check through options

 = 1 + 1 3 + 1 (9 + 4/9)

 = 1 3 + 9 13

 = 1 39 + 9 13

 = 13 48

1. simplifies to

1. Suppose that

 ∴ a2 − b2 = (a + b)(a − b) (a + b) (a + b)

= (a – b)
 = 111 − 91 = 20 101 101 101

##### Correct Option: C

Suppose that

 ∴ a2 − b2 = (a + b)(a − b) (a + b) (a + b)

= (a – b)
 = 111 − 91 = 20 101 101 101

1. is simplified to

1.  = 2 2 + 11 × 2 × 0.39 39

 = 2 2 + 11 × 2 × 39 39 100

 = 2 2 + 11 50

 = 2 100 +11 50

 = 100 111

##### Correct Option: D

 = 2 2 + 11 × 2 × 0.39 39

 = 2 2 + 11 × 2 × 39 39 100

 = 2 2 + 11 50

 = 2 100 +11 50

 = 100 111

1.  Expression = 1 + 1 1 + 1 2

 = 1 + 1 2 +1 2

 = 1 + 2 = 3 + 2 = 5 3 3 3

##### Correct Option: D

 Expression = 1 + 1 1 + 1 2

 = 1 + 1 2 +1 2

 = 1 + 2 = 3 + 2 = 5 3 3 3

1. Expression

 = 38 33 99 + 10 33

 = 38 × 33 = 38 33 109 109

##### Correct Option: A

Expression

 = 38 33 99 + 10 33

 = 38 × 33 = 38 33 109 109
