Sagot :

To find the value of the given expression [tex]\[(-17) \times(-4) \times(-1) \times(-5) - (-15) \times (-3) \times 0 \times (-13) \times (-11),\][/tex] we can break it down into two parts:

1. Calculate the first part:
[tex]\[ (-17) \times (-4) \times (-1) \times (-5) \][/tex]
- Multiplying two negative numbers results in a positive number:
[tex]\[ (-17) \times (-4) = 68 \][/tex]
- Now, multiplying 68 with [tex]\(-1\)[/tex] results in a negative number:
[tex]\[ 68 \times (-1) = -68 \][/tex]
- Finally, multiplying [tex]\(-68\)[/tex] with [tex]\(-5\)[/tex] results in a positive number:
[tex]\[ -68 \times (-5) = 340 \][/tex]
So, the first part of the expression evaluates to 340.

2. Calculate the second part:
[tex]\[ (-15) \times (-3) \times 0 \times (-13) \times (-11) \][/tex]
- Here, one of the factors is 0. When any number is multiplied by 0, the result is always 0:
[tex]\[ (-15) \times (-3) \times 0 \times (-13) \times (-11) = 0 \][/tex]
So, the second part of the expression evaluates to 0.

3. Combine the results of the two parts:
[tex]\[ 340 - 0 = 340 \][/tex]

Therefore, the value of the given expression is [tex]\(\boxed{340}\)[/tex].
