If (৪)×(16)×(32)×(64) = 2(x + y) What is the average of x and y?
Solution
Correct Answer: Option B
(৪)×(16)×(32)×(64) = 2(x + y)
⇒ 23 × 24 × 25 × 26 = 2(x + y)
⇒ 218 = 2(x + y)
⇒ 18 = x + y
∴ x এবং y এর গড় = (x + y)/2 = 18/2 = 9
⇒ 23 × 24 × 25 × 26 = 2(x + y)
⇒ 218 = 2(x + y)
⇒ 18 = x + y
∴ x এবং y এর গড় = (x + y)/2 = 18/2 = 9
