Find the value of \(22^2+11^3\).

Answer and explanation

Correct answer: 1815

Compute each power separately. \(22^2=22\times22=484\) and \(11^3=11\times11\times11=11\times121=1331\). Adding gives \(484+1331=1815\). Option B (1805) is wrong — it likely comes from a small arithmetic slip when computing the cube or the final addition. Exam tip: calculate powers one at a time and verify by checking last digits or re-adding to catch simple mistakes.
