(x + 2)^5=(x+2)^2\cdot{(x+2)^2}\cdot{(x+2)}\\\\(x+2)^5=(x^2+4x+4)\cdot{(x^2+4x+4)}\cdot(x+2)

(x+2)^5=(x^4+8x^3+24x^2+32x+16)\cdot(x+2)

(x+2)^5=x^5+10x^4+40x^3+80x^2+80x+32

How many zero arin the product of any whole. number less than 10 and 500
Stolb23 [73]

Answer:

Hay un máximo de tres ceros en el producto de un número distinto de cero cero menor que 10 y 500

Para poder ver esto, la forma más fácil para resolver este problema es multiplicar todos los números entre 1 y 9 por 500, es decir:

01*500 = 500

2*500 = 1.000

3*500 = 1.500

4*500 = 2.000

5*500 = 2.500

6*500 = 3.000

7*500 = 3.500

8*500 = 4.000

9*500 = 4.500

Como vemos, si multiplicamos a 500 por cualquier número par, entonces obtenemos un número con tres ceros, mientras que si este es impar solamente obtenemos dos ceros
