80 divided by ( 4 exponent 2 divided by 2/5) + 3.75
To solve this expression, let's break it down step by step:
1. First, calculate the exponent: 4 exponent 2 = 4^2 = 16.
2. Now, divide 16 by 2/5: 16 ÷ (2/5) = 16 × (5/2) = 16 × 5/2 = 80/2 = 40.
3. Finally, add 3.75 to 40: 40 + 3.75 = 43.75.
Therefore, the result is 43.75.
