Question

Find the value of Y if (3/11)2y×(3/11)3=(3/11)7
​

Answer 1

Answer:

∴ Value of Y is 4.28

Step-by-step explanation:

Given: (3/11)2y×(3/11)3=(3/11)7

⇒ 3 / 11 (2y) × 3 / 11 (3) = 3 / 11 (7)

⇒ 3 / 11  (2y) × 9 / 11  =  21 / 11

⇒ 3 / 11 (2y) = 21 / 11 × 11 / 9

⇒ 3 / 11 (2y) = 21 / 9

⇒ 2y = 21 / 9 × 11 / 3

⇒ 2y = 7 / 9 × 11

⇒ 2y  = 0.78 × 11  ...[7 / 9 = 0.77 = 0.78]

⇒ y = 8.58 / 2

⇒ y = 4.28

∴ Value of Y is 4.28
