What is the value of \(2^6 + 3^4\)?
Answer and explanation
Correct answer: 145
Compute the powers first: \(2^6=64\) and \(3^4=81\). Adding them gives \(64+81=145\), so 145 is correct. Common wrong choices (e.g. 135 or 155) arise from mis-evaluating a power or a single-digit addition error. Exam tip: memorize small powers and recheck the final addition quickly to avoid slip errors.
