Answer 1

1) 

3³ . 18 + 72 . 4² - 41 . 18

= 3³ . 18 + 18 . 4³ - 41 . 18

= 18 . ( 3³ + 4³ - 41 )

= 18 . 50

= 900

2) ( 56 . 46 - 25 . 23 ) : 23

= ( 112 . 23 - 25 . 23 ) : 23

= ( 112 - 25 ) . 23 : 23

= 87 . 23 : 23

= 87

3) ( 76 . 34 - 19 . 64 ) : ( 38 . 9 )

= ( 19 . 136 - 19 . 64 ) : ( 19 . 18 )

= 19 . ( 136 - 64 ) : ( 19 . 18 )

= 19 . 72 : 19 . 18

= 19 . 4

= 76

4) ( 5 . 4¹¹ - 3 . 16⁵ ) : 4¹⁰

= ( 5 . 4¹¹ - 3 . 4¹⁰ ) : 4¹⁰

= ( 20 . 4¹⁰ - 3 . 4¹⁰ ) : 4¹⁰

= ( 20 - 3 ) . 4¹⁰ : 4¹⁰

= 17
