검증된 단계별 안내1
Identify the expression given: \$4(0)$, which represents the product of 4 and 0.
Recall the multiplication property that any number multiplied by zero equals zero.
Apply this property to the expression: multiply 4 by 0.
Write the product as \(4 \times 0\).
Conclude that the product is 0, since multiplying by zero always results in zero.
