Question

1*) Simplifique as expressões dadas :

a) { 120 ÷ [ V 25 × ( 5 ^2 + 8 ÷ 2 - V 16 - 1^6 ) ] }

b) { 64 - [ 3^ V 64 + ( 12 ÷ V 9 + 6^2 - 30 ) ] }

Answer 1

a)

= { 120 ÷ [ V 25 × ( 5 ^2 + 8 ÷ 2 - V 16 - 1^6 ) ] }

= {120 : [ 5 . (25 + 8 : 2 - 4 - 1)]}

= {120 : [ 5 . (25 + 4 - 4 - 1)]}

= {120 : [ 5 . (25 - 1)]}

= {120 : [ 5 . 24]}

= 120 : 120

= 1

b)

Esse 3^ seria elevado?

= { 64 - [ 3^ V 64 + ( 12 ÷ V 9 + 6^2 - 30 ) ] }

= { 64 - [ 3^ 8 + (12 : 3 + 36 - 30)]}

= { 64 - [6561 + (4 + 6)]}

= {64 - [6561 + 10]}

= 64 - 6571

= - 6507
