Enter the complex conjugate of the following expression. -2+sqrt (7)i

The complex conjugate of a complex number \(a + bi\) is \(a - bi\).<br /><br />Given the complex number \(-2 + \sqrt{7}i\), its complex conjugate is:<br /><br />\[<br />-2 - \sqrt{7}i<br />\]<br /><br />So, the complex conjugate of \(-2 + \sqrt{7}i\) is \(-2 - \sqrt{7}i\).
