₀^ 3 2 [ 2 x ] d x , where [ ] denotes the greatest integer function, is equal to
Options
- A2 ( 1+ 1)
- B2 ( 1+ 2)
- C2 ( 1- 1)
- D2 ( + 2)
Correct answer
B. 2 ( 1+ 2)
Step-by-step solution
aligned & ₀^ 3 2 ( 2 x ) d x= ₀^ 2 ( 2 x ) d x+ _ 2 ^ ( 2 x ) d x & + _ ^ 3 2 ( 2 x ) d x & =0+ 1 _ 2 ^ d x+ 2 _ ^ 3 2 d x & aligned = 2 ( 1+ 2)
