Each question has three possible distinct answers.
Ten questions have 3^10 possible distinct answers sheets.
=>
(3^10)+3 will guarantee that at least 3 answer sheets are identical.
Numerically,
(3^10)+3 = 59049 +3 = 59052

Answer:
- Lena's Method: 280
- Jackson's Method: 280
Step-by-step explanation:
Lena's Method:
- 8 + 12 = 20
- Plug 20 in: 14(20)
- 14(20) = 14 × 20 = 280
Jackson's Method:
- 14 × 8 = 112
- 14 × 12 = 168
- Re-write the expression: 112 + 168
- 112 + 168 = 280
