- The given equation is structured as: \((8)^3 = (26)^2 - 43\).

- Start by calculating \( (8)^3 \), which equals \( 512 \).

- Next, calculate \( (26)^2 \), which equals \( 676 \).

- Subtract \( 43 \) from \( 676 \), resulting in \( 633 \).

- Set \( 512 + ? = 633 \).

- Therefore, solving for the question mark results in \( ? = 633 - 512 \), which equals \( 121 \).

- Option 1, 121: This is correct.

- Option 2, 131

- Option 3, 111

- Option 4, 119
