Q13 verify the associative law of multiplication for in tegess \( -2,55 \) and -3 .

To verify the associative law of multiplication, we need to show that \((-2.55 \times -3) \times a = -2.55 \times (-3 \times a)\) for any integer \(a\). Let’s use \(a = 1\) for simplicity. First, calculate \((-2.55 \times -3) \times 1\): \[ -2.55 \times -3 = 7.65 \] So, \(7.65 \times 1 = 7.65\). Now, calculate \(-2.55 \times (-3 \times 1)\): \[ -3 \times 1 = -3 \quad \text{and}\quad -2.55 \times -3 = 7.65. \] Both expressions equal \(7.65\), thus proving the associative law holds for these numbers! Now, if we wanted to include more integers we could check other values to absolutely confirm the associative property. It’s a great way to bolster understanding!
