Question

calcule: fatorial 12!x3! sobre 15!

Answer 1

Olá,

$\frac{12! * 3!}{15!} = \frac{12!*3!}{15*14*13*12!} \\\\ \frac{3!}{15*14*13} \\\\ \frac{3*2*1}{15*14*13} \\\\ \frac{3}{15*7*13} \\\\ \frac{1}{5*7*13} \\\\ \frac{1}{455}$

Bons estudos ;)

Answer 2

$\dfrac{12! \times 3!}{15!} =\\\\\\ \dfrac{2.874.009.600}{1307674368000}=0,002197$

Forte abraço!
