3^4^3^4 ➖ 3^4^3^4^3^4 1^2^2^1^2^2 ➖ 1^2^2^1^2^2^3^2^2 1^1^1^1 ➖ 1^1^1^1^3^1^2 3^2 (x ➖ 3x+2).

Bấm máy tính cho đỡ mất thời gian 😅😅😅

7(7^6 -111)
=7(343 × 343 -111)
=7(117649 - 111)
=7×117538
=822766
Use long multiplication to find 343 × 343

[@JoseLuisGomezVelasquez]

Efectuar:7⁷-7.7.7
=7⁷-7³=7³(7⁴-7)
=343(2.401-7)
=343.2394=821.242
R:821.242✓
