If 3a × 812a = 276, then find the value of a.1. 22. 03. 34. 1

Answer» Correct Answer - Option 1 : 2

Given:

3a × 812a = 276

Concept:

Ax × Ay = Ax + y

If Bp = Bq, then p = q

Calculation:

3a × 812a = 276

⇒ 3a × 34(2a) = 33 × 6

⇒ 3a × 38a = 318

⇒ 3a + 8a = 318

Now, Bp = Bq

⇒ 9a = 18

⇒ a = 2

The value of a is 2.
