Prvo rješenje.

$$\begin{aligned} &77\cdot16\cdot19+88\cdot(-7\cdot6^2)+99\cdot2^3\cdot(77-19\cdot4)\\ &=7\cdot11\cdot2\cdot8\cdot19+88\cdot(-7\cdot36)+9\cdot11\cdot8\cdot(77-76)\\ &=7\cdot11\cdot2\cdot8\cdot19+88\cdot(-7\cdot2\cdot2\cdot9)+9\cdot11\cdot8\cdot1\\ &=88\cdot7\cdot2\cdot19-88\cdot7\cdot2\cdot18+88\cdot9\\ &=88\cdot(14\cdot19-14\cdot18+9)\\ &=88\cdot(14\cdot(19-18)+9)\\ &=88\cdot(14\cdot1+9)\\ &=88\cdot23=2024. \end{aligned}$$

Drugo rješenje.

$$\begin{aligned} &77\cdot16\cdot19+88\cdot(-7\cdot6^2)+99\cdot2^3\cdot(77-19\cdot4)\\ &=77\cdot16\cdot19+88\cdot(-7\cdot36)+99\cdot8\cdot(77-76)\\ &=77\cdot16\cdot19+88\cdot(-7\cdot36)+99\cdot8\cdot1\\ &=23408-22176+792\\ &=1232+792\\ &=2024. \end{aligned}$$
