Question

2.[(95+5²:5):2³+180]-2³.10²

 

Answer 1

2 . [( 95 + 25 : 5 ) : 8 + 180 ] - 8 . 100

= 2 . [( 95 + 5 ) : 8 + 180 ] - 800

= 2 . ( 100 : 8 + 180 ) - 800

= 2 . ( 12,5 + 180 ) - 800

= 2 . 192,5 - 800

= 385 - 800

= -415 

Answer 2

2.[(95+5²:5):2³+180]-2³.10²

=2.[(95+5):8+180]-8.100

=2.(100:8+180)-800

=2.(12,5+180)-800

=2.192,5-800

=385-800

=-415
