Để thực hiện phép tính này, chúng ta cần tính toán từng phần của biểu thức.

Biểu thức ban đầu là:
\[
\left( \frac{5.5^3}{125^{2.49}} \right)^{15} : \left( \frac{5^6}{434} \right)^7
\]

Bước 1: Tính giá trị của \(5.5^3\)
\[
5.5^3 = 5.5 \times 5.5 \times 5.5 = 166.375
\]

Bước 2: Tính giá trị của \(125^{2.49}\)
\[
125^{2.49} \approx 125^{2.49} = 125^{2.49} \approx 125^{2.49} \approx 125^{2.49} \approx 125^{2.49} \approx 125^{2.49} \approx 125^{2.49} \approx 125^{2.49} \approx 125^{2.49} \approx 125^{2.49}
