Respuesta:

4º) 168

5º) 21

6º) 1127

7º) 225

Explicación paso a paso:

4º) (30 + 5) ÷ [5 x (4 - 3)] x [(6 x 8) ÷ (6 ÷ 3)]

(30 + 5) ÷ [5 x (1)] x [(48) ÷ (2)]

(35) ÷ [5] x [24]

35 ÷ 5 x 24

7 x 24

168

5º) (28 - 7) x {[(28 ÷ 4) x 7] ÷ (14 ÷ 2) ÷ 7}

(28 - 7) x {[7 x 7] ÷ (14 ÷ 2) ÷ 7}

(28 - 7) x {[49] ÷ (7) ÷ 7}

(28 - 7) x {7 ÷ 7}

(21) x {1}

21 x 1

21

6º) [3 x (5 x 3) x 25] + [(24 ÷ 6) ÷ (8 ÷ 4)]

[3 x (15) x 25] + [(4) ÷ (2)]

[45 x 25] + [2]

[1125] + [2]

1125 + 2

1127

7º) (90 ÷ 6) x {-2 + [3 x (5 + 1) - (8 - 4) + 3]}

(90 ÷ 6) x {-2 + [3 x (6) - (4) + 3]}

(90 ÷ 6) x {-2 + [18 - 4 + 3]}

(90 ÷ 6) x {-2 + [14 + 3]}

(90 ÷ 6) x {-2 + [17]}

(15) x {15}

15 x 15

225
