Options
- A. 1 36
- B. 1 16
- C. 1 9
- D. 1 4
Answer
D. 1 4
Step-by-step solution
1 = RZ ^2 ( 1 n _1^2 - 1 n _2^2 ) For 2 3 1 _1 = R (1)^2 ( 1 2^2 - 1 3^2 ) (1) For 4 6 1 _2 = R (1)^2 ( 1 4^2 - 1 6^2 ) (2) Divide (1) & (2) aligned & _2 _1 = 1 2^2 - 1 3^2 1 4^2 - 1 6^2 \\ & _2 _1 = 4 1 \\ & _1 _2 = 1 4 aligned
