Calculeaza. h) 9+8x[7+6x(5+4x3)-2x1]-10x10=?

Answer 1

   

h)  

9 + 8 × [7 + 6 × (5 + 4 × 3) - 2 × 1] - 10 × 10 =

= 9 + 8 × [7 + 6 × (5 + 12) - 2 × 1] - 10 × 10 =

= 9 + 8 × [7 + 6 × 17 - 2 × 1 ] - 10 × 10 =

= 9 + 8 × [7 + 102 - 2] - 100 =

= 9 + 8 × 107 - 100 =

= 9 + 856 - 100 = 765

Answer 2

Răspuns:

765

Explicație pas cu pas:

9+8x[7+6x(5+4x3)-2x1]-10x10=

=9+8x[7+6x(5+12)-2x1]-10x10=

=9+8x(7+6x17-2x1)-10x10=

=9+8x(7+102-2)-10x10=

=9+8x(109-2)-10x10=

=9+8x107-10x10=

=9+856-100=

=865-100=

=765
