What is the value of \(6^4 + 3^5\)?
Answer and explanation
Correct answer: 1539
Compute each power first: \(6^4=6\times6\times6\times6=1296\) and \(3^5=3\times3\times3\times3\times3=243\). Adding gives \(1296+243=1539\). Option B (1536) is a close arithmetic mistake (treating 243 as 240). Option A (1296) is just \(6^4\) alone. Exam tip: evaluate powers separately and then add; checking the units digit often catches small addition errors.
