Koraci rješenja

Izrazite \frac{\frac{\frac{7\times 8\times 9\times 10\times 11\times 12\times 13}{39}}{40}}{42} kao jedan razlomak.

$$\frac{\frac{7\times 8\times 9\times 10\times 11\times 12\times 13}{39}}{40\times 42}$$

Pomnožite 7 i 8 da biste dobili 56.

$$\frac{\frac{56\times 9\times 10\times 11\times 12\times 13}{39}}{40\times 42}$$

Pomnožite 56 i 9 da biste dobili 504.

$$\frac{\frac{504\times 10\times 11\times 12\times 13}{39}}{40\times 42}$$

Pomnožite 504 i 10 da biste dobili 5040.

$$\frac{\frac{5040\times 11\times 12\times 13}{39}}{40\times 42}$$

Pomnožite 5040 i 11 da biste dobili 55440.

$$\frac{\frac{55440\times 12\times 13}{39}}{40\times 42}$$

Pomnožite 55440 i 12 da biste dobili 665280.

$$\frac{\frac{665280\times 13}{39}}{40\times 42}$$

Pomnožite 665280 i 13 da biste dobili 8648640.

$$\frac{\frac{8648640}{39}}{40\times 42}$$

Podijelite 8648640 s 39 da biste dobili 221760.

$$\frac{221760}{40\times 42}$$

Pomnožite 40 i 42 da biste dobili 1680.

$$\frac{221760}{1680}$$

Podijelite 221760 s 1680 da biste dobili 132.

$$132$$
