Explicație pas cu pas:
2^4×3^2 - 2^4 = 2^4 × ( 3^2-1 ) = 2^4 × ( 9-1 ) = 2^4 ×8 = 2^4 × 2^3 = 2^7
7^5×7^6×7- 7^3×7^6×7^2 × 7 = 7^12 - 7^12 = 0
(5^3)^4 : 5^11 = 5^12 : 5^11 = 5^1 = 5
(2^3)^5 : (2^4) ^3 = 2^15 : 2^12 = 2^3 = 8
(1+3^14:3^9) : ( 1+3^4×3^2 :3) = ( 1 + 3^5 ) : ( 1 + 3^6 : 3 ) = ( 1 + 3^5 ) : ( 1 + 3^5 ) = 1
