Sagot :

Certainly! Let's simplify the given expression step by step:

The expression we need to simplify is:

[tex]\[ \frac{8|7 + (-10)|}{2 \cdot 3^2} \][/tex]

### Step 1: Simplify inside the absolute value
First, we handle the expression inside the absolute value:

[tex]\[ 7 + (-10) = 7 - 10 = -3 \][/tex]

### Step 2: Apply the absolute value
The absolute value of [tex]\(-3\)[/tex] is:

[tex]\[ | -3 | = 3 \][/tex]

### Step 3: Substitute back into the expression
Next, we substitute this absolute value back into the original expression:

[tex]\[ \frac{8 \times 3}{2 \cdot 3^2} \][/tex]

### Step 4: Simplify the denominator
Calculate [tex]\(3^2\)[/tex]:

[tex]\[ 3^2 = 9 \][/tex]

So the denominator becomes:

[tex]\[ 2 \cdot 9 = 18 \][/tex]

### Step 5: Simplify the numerator
The numerator simplifies to:

[tex]\[ 8 \times 3 = 24 \][/tex]

### Step 6: Divide the numerator by the denominator
Finally, we divide the simplified numerator by the simplified denominator:

[tex]\[ \frac{24}{18} = \frac{4}{3} \][/tex]

Therefore, the simplified value of the given expression is:

[tex]\[ \boxed{\frac{4}{3}} \][/tex]

This matches one of the given answer choices.
