If \[\mathbf{x=}\sqrt{\mathbf{13}}\mathbf{-}\sqrt{\mathbf{11}}\] and \[\mathbf{y=}\sqrt{\mathbf{13}}\mathbf{+}\sqrt{\mathbf{11}}\], then find the value of \[\mathbf{(}{{\mathbf{x}}^{\mathbf{3}}}\mathbf{+80}\sqrt{\mathbf{11}}\mathbf{)-(}{{\mathbf{y}}^{\mathbf{3}}}\mathbf{-20}\sqrt{\mathbf{11}}\mathbf{)}\]
