Question

4) Calculeaza a) 3024•58+3024•43-3024= b) [8+8•(8/98:8/96)]:129

Answer 1

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

b)

[ 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
