a)
3 024 • 58 + 3 024 • 43 - 3 024= 302 400
= 3 024 • ( 58 + 43 - 1 ) =
= 3 024 • ( 101 - 1 ) =
= 3 024 • 100 =
= 302 400

[ 8 + 8 x ( 8² + 8⁹⁸ : 8⁹⁶ ) ] : 129 =
= [ 8 + 8 x ( 64 + 8²) ] : 129 =
= [ 8 + 8 x ( 64 + 64 ) ] : 129 =
= ( 8 + 8 x 128 ) : 129 =
= 8 x ( 1 + 128 ) : 129 =
= 8 x 129 : 129 =
= 8
