To solve the expression \(8 - 3\sqrt{16}\), we need to follow these steps:<br /><br />1. Calculate the square root of 16.<br />2. Multiply the result by 3.<br />3. Subtract the result from 8.<br /><br />Let's go steps:<br /><br />1. \(\sqrt{16} = 4\)<br />2. \(3 \times 4 = 12\)<br />3. \(8 - 12 = -4\)<br /><br />So, the value of the expression \(8 - 3\sqrt{16}\) is \(-4\).<br /><br />Therefore, the correct answer is:<br />B. \(-4\)
