If | a |= 27 ,| b |=7 and | a b |=35 , then a b is equal to
Options
- A35 2
- B35 2
- C7 2
- D35
Correct answer
C. 7 2
Step-by-step solution
| a |= 27 ,| b |=7 and | a b |=35 We know that array rlrl & | a b | & =| a || b | & & = | a b | | a || b | = 35 27 7 = 5 27 & = 1- 25 27 = 2 27 array Now, aligned a b & =| a || b | & = 27 7 2 27 =7 2 aligned
