\[\boxed{\mathbf{6}.}\]

\[\textbf{а)}\ 134 - (65 + 34) =\]

\[= (134 - 34) - 65 =\]

\[= 100 - 65 = 35\]

\[\textbf{б)}\ 157 - (57 + 76) =\]

\[= (157 - 57) - 76 =\]

\[= 100 - 76 = 24\]

\[\boxed{\mathbf{7}.}\]

\[\textbf{а)}\ 226 - 73 - 27 = 226 -\]

\[- (73 + 27) = 226 - 100 = 126\]

\[\textbf{б)}\ 348 - 25 - 75 = 348 -\]

\[- (25 + 75) = 348 - 100 = 248\]

\[\boxed{\mathbf{8}.}\]

\[\textbf{а)}\ (237 + 66) - 37 =\]

\[= (237 - 37) + 66 =\]

\[= 200 + 66 = 266\]

\[\textbf{б)}\ (141 + 184) - 84 = 141 +\]

\[+ (184 - 84) = 141 + 100 = 241\]

\[\textbf{в)}\ (516 + 39) - 16 =\]

\[= (516 - 16) + 39 =\]

\[= 500 + 39 = 539\]

\[\textbf{г)}\ (825 + 273) - 73 = 825 +\]

\[+ (273 - 73) = 825 + 200 =\]

\[= 1025\]
