If 22a + 3 ÷ 16 = 2a + 1, then find the value of a.1. 32. 43. 24. 1

Answer» Correct Answer - Option 3 : 2

Given:

22a + 3 ÷ 64 = 2a + 1

Concept:

Ax ÷ Ay = Ax – y

If Bp = Bq, then p = q

Calculation:

22a + 3 ÷ 16 = 2a + 1

⇒ 22a + 3 ÷ 24 = 2a + 1

⇒ 22a + 3 – 4 = 2a + 1

⇒ 22a – 1 = 2a + 1

Now, Bp = Bq

⇒ 2a – 1 = a + 1

⇒ a = 2

The value of a is 2.
