Using this notation A⊕B means A ÷ B A⊖B means A + B A⊗B means A − B A⨸B means A × B A (∧) B means B^A (57 ⊕ 3 ⊖ 6 ⊗ 9 ⨸ 3) (∧) 2 =
- 1 ⨸ 4
- 1 (∧) 4
- 1 ⊕ 4
- 4 ⊗ 1
ఈ సంజ్ఞామానం ఉపయోగించి A⊕B అంటే A ÷ B A⊖B అంటే A + B A⊗B అంటే A − B A⨸B అంటే A × B A (∧) B అంటే B^A (57 ⊕ 3 ⊖ 6 ⊗ 9 ⨸ 3) (∧) 2 =
- 1 ⨸ 4
- 1 (∧) 4
- 1 ⊕ 4
- 4 ⊗ 1

Answer: (3) 1 ⊕ 4
సమాధానం: (3) 1 ⊕ 4
In this notation ⊕ (circled plus) stands for ÷, ⊖ (circled minus) for +, ⊗ (circled times) for −, ⨸ (circled division sign) for ×, and (∧), printed as a circle with ∧ inside, means A (∧) B = B^A. Decoding the bracket gives 57 ÷ 3 + 6 − 9 × 3 = 19 + 6 − 27 = −2, so (−2) (∧) 2 = 2^(−2) = 1/4. That is 1 ÷ 4, which is written 1 ⊕ 4.
