If (e^2=1849) then what is the positive value of (e)?
Answer and explanation
Correct answer: 43
Given \(e^2=1849\), the positive value of \(e\) is the positive square root of 1849. Since \(43^2=43\times43=1849\), we get \(e=43\). The closest distractor, 42, is incorrect because \(42^2=1764\), not 1849. Exam tip: when a variable has a positive square value, check the positive integer whose square equals the given number.
