Question

Вычеслите 10!+9!/7!

Answer 1

10!+(7!*2!)/7!=2!*8!+2!=2!*(8!+1)=2*(2*3*4*5*6*7*8+1)= 2*40321=80642

Answer 2

To calculate the expression, let's first find the factorial of each number:

10! = 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 3,628,800

9! = 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 362,880

7! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5,040

Now, we can substitute these values into the expression:

10! + 9!/7! = 3,628,800 + 362,880 / 5,040

Now, perform the division:

10! + 9!/7! = 3,628,800 + 72

Finally, add the numbers together:

10! + 9!/7! = 3,628,800 + 72 = 3,628,872

So, the result of the expression is 3,628,872.
