0.98[8698883 (1.187 ^2-1+3.71*1.187 ^2(ln(1.187 ))/(1379.0 (520.00 -438.000 )(1+1.86*1.187 ^2))]

Let's break down and simplify the given expression step by step. The expression is:

\[0.98 \left[8698883 \left(1.187^2 - 1 + 3.71 \cdot 1.187^2 \frac{\ln(1.187)}{1379.0 \left(520.00 - 438.000\right) \left(1 + 1.86 \cdot 1.187^2\right)}\right)\right]\]

First, simplify the constants and smaller expressions:

1. \(1.187^2\):
\[1.187^2 = 1.409169\]

2. \(520.00 - 438.000\):
\[520.00 - 438.000 = 82.00\]

3. \(1.86 \cdot 1.187^2\):
\[1.86 \cdot 1.409169 = 2.62242834\]

4. \(\ln(1.187)\):
\[\ln(1.187) \approx 0.171850256\]

Next, substitute these simplified values back into the expression:

\[0.98 \left[8698883 \left(1.409169 - 1 + 3.71 \cdot 1.409169 \frac{0.171850256}{1379.0 \cdot 82.00 \left(1 + 2.62242834\right)}\right)\right]\]

Calculate the denominator:

\[1379.0 \cdot 82.00 = 113078.0\]
\[1 + 2.62242834 = 3.62242834\]
\[113078.0 \cdot 3.62242834 = 409737.85652\]

Now, simplify the fraction:

\[\frac{0.171850256}{409737.85652} \approx 4.1931 \times 10^{-7}\]

Calculate the term inside the parentheses:

\[3.71 \cdot 1.409169 \cdot 4.1931 \times 10^{-7} \approx 2.1876 \times 10^{-6}\]

Add the terms:

\[1.409169 - 1 + 2.1876 \times 10^{-6} \approx 0.4091711876\]

Now multiply by 8698883:

\[8698883 \cdot 0.4091711876 \approx 3557781.39\]

Finally, multiply by 0.98:

\[0.98 \cdot 3557781.39 \approx 3486625.76\]

So, the value of the given expression is approximately \(3486625.76\).
