Step-by-step explanation:

1. First of all do the factors of 4 as well as 32 on both the sides.

  • 2^2(2x-1) ≤ 2^5

2. Now simplify the left side.

  • 2^4x-2 ≤ 2^5

3. Base is same on both sides i.e. 2. So powers of 2 on both sides put to be equal.

  • 4x-2 = 5

4. Now, add 2 on both sides.

  • 4x-2+2 = 5+2
  • 4x = 7

5. Dividing by 4 on both sides.

  • 4x/4 ≤ 7/4
  • x = 7/4

This is the required answer –– x = 7/4
