Hi!

We can use PEMDAS to solve this
7 + (2 + 6)2 ÷ 4 · \(\frac{1}{2}^{4}\)
Since \(\frac{1}{2}\) is equal to 0.5..
7 + (2 + 6)2 ÷ 4 · \(0.5^{4}\)
Parentheses
7 + 8 · 2 ÷ 4 · \(0.5^{4}\)
Exponents
7 + 8 · 2 ÷ 4 · 0.0625
Multiplication
7 + 16 ÷ 0.25
Division
7 + 64
Addition
71

The answer is 71

Hope this helps! :)
