If (y^2=1369) then what is the positive value of (y)?

Answer and explanation

Correct answer: 37

Since \(37^2=37\times37=1369\), the positive solution of \(y^2=1369\) is \(y=37\). The negative solution \(-37\) is also possible, but the question asks for the positive value. Exam tip: verify a square-root answer by squaring it.
