Nice factorization! Love this observation which avoids having to multiply out all the numbers.
3 ⨂ 4
= 3 4 − 4 3
= 1 7
3 3 3*3=81
4 4 4=64
81-64=17
3^4 - 4^3 = 81 - 64
81 - 64 = 17
(3^4) - (4^3)
= 81 - 64
= 17
3^4-4^3=3 3 3 3-4 4*4=81-64=17
3X4=3^4 - 4^3=9^2 - 8^2=(9-8)(9+8)=17
a⊗b=a^b−b^a then >>> 3⊗4 means 3^4-4^3 = 17 answer is =17
3 x 4=3.3.3.3 - 4.4.4 3 x 4=81 - 64 3 x 4 = 17 Resultado 17
3⊗4=3^4-4^3=81-64=17 To make it clarified: The symbol (^) represents an exponent. FOR THE LONG METHOD: 3⊗4=3 3 3 3-4 4*4 =81-64 =17
hey i'd also done like that
3^4 - 4^3 = 81-64 = 17
3 ⊗ 4 = 3^4 - 4^3 = 81 - 64 = 17

It is the same as 3 4 − 4 3 which is equal to ( 3 2 × 3 2 ) − ( 4 2 × 4 ) so ( 9 × 9 ) − ( 1 6 × 4 ) = 8 1 − 6 4 = 1 7
Answer: 1 7
