Langkah Solusi

Evaluate trigonometric functions in the problem

$$0,573576436351046 \cdot 0,9961946980917455 - 0,08715574274765817 \cdot 0,8191520442889918$$

Kalikan 0,573576436351046 dan 0,9961946980917455 untuk mendapatkan 0,571393804843269548895352890793.

$$0,571393804843269548895352890793-0,08715574274765817\times 0,8191520442889918$$

Kalikan 0,08715574274765817 dan 0,8191520442889918 untuk mendapatkan 0,071393804843269661145782160333006.

$$0,571393804843269548895352890793-0,071393804843269661145782160333006$$

Kurangi 0,071393804843269661145782160333006 dari 0,571393804843269548895352890793 untuk mendapatkan 0,499999999999999887749570730459994.

$$0,499999999999999887749570730459994$$

Faktor

$$\frac{11 \cdot 97 \cdot 3671 \cdot 1241203 \cdot 6231776611 \cdot 8251568537}{2 ^ {32} \cdot 5 ^ {33}} = 0,49999999999999983$$
