Question

Resolva as expressões numéricas:


a) 45 - {18 + [20 - 3 x ( 5+ 10 : 10)] - 6} =


b) [ √100– (24– 8) · 2 – 24 ] ÷ (22– 3 + 2) =


c) ( 16 + 3² x 2³) - ( 5 + 3¹ x 6) =​

Answer 1

Explicação passo-a-passo:

a) 45 - {18 + [20 - 3 x ( 5+ 10 : 10)] - 6} =

45-{18+[20-3x (5+1)]-6}

45-{18+[20-3x6]-6}

45-{18+[20-18]-6}

45-{18+2-6}

45-10

b) [ √100– (24– 8) · 2 – 24 ] ÷ (22– 3 + 2) =

[√100 - 16 . 2-24] : 21

[10-32-24]:21

c) ( 16 + 3² x 2³) - ( 5 + 3¹ x 6) =​

(16+3.3 . 2.2.2) - ( 5+3.6)

(16+9.8) - (5+18)

(16+72)-23
