Assessment: WAEC SSCE - General Mathematics - 2015 (Objective) Subject: General Mathematics

Question 1 Report

If 2n = y, Find 2\(^{(2 + \frac{n}{3})}\)
Answer Details
We know that 2\(^n\) = y. Therefore, 2\(^{(2 + \frac{n}{3})}\) can be written as 2\(^2\) × 2\(^{\frac{n}{3}}\) = 4 × 2\(^{\frac{n}{3}}\). Substituting 2\(^n\) = y in the above equation, we get: 2\(^{(2 + \frac{n}{3})}\) = 4y\(^\frac{1}{3}\) Therefore, the answer is (a) 4y\(^\frac{1}{3}\).
