simplify (6!)/(1!)

Solution

simplify

\frac{6 !}{1 !}

720

Solution steps

\frac{6 !}{1 !}

Cancel the factorials:

\frac{n !}{( n - m ) !} = n \cdot (n - 1) \dots (n - m + 1), n > m

\frac{6 !}{1 !} = 6 \cdot 5 \cdot 4 \cdot 3 \cdot 2

= 6 \cdot 5 \cdot 4 \cdot 3 \cdot 2

Multiply the numbers:

6 \cdot 5 \cdot 4 \cdot 3 \cdot 2 = 720

= 720

(- 4) (4 - 25)

\frac{1}{5} \div 5

2^{x} - 2^{- x}

(5 - 45) (- 2 + 5)

\frac{4}{7 + 3}
