Question

REALIZA CADA OPERCACION TENIENDO EN CUENTA LA JERARQUIA

Answer 1

Explicación paso a paso:

1.

a. (–15)(2)–(–16)/(–8)

(–30)–2=–32

b. (–12)+(–9)(6)/(–2)

–12+(–54)/(–2) = –12+27 = 15

c. 7–3(–4)–27/(–9)

7–(–12)–(–3) = 7+12+3 = 22

d. (–45)–(–49)/7(–6)

–45–(–7)(–6) = –45–(+42) = –45–42 = –87

e. (-20)+6(–5)/(–2)

–20+(–30)/(–2) = –20+15 = –5

2.

a. (3–8)+[5–(–2)]

–5+[5+2] = –5+7 = 2

b. 5–[63–2–(12–8)–3+6]

5–[61–(4)–9] = 5–[57–9] = 5–48 = –43

c. 18/[12/(–2)]

18/(–6) = –3

d. (5+3(2)/6–4)(4/2–3+6)

(5+6/6–4)(2–9) = (5+1–4)(–7) = (2)(–7) = –14

3.

a. 15+18/3 = (15+18)/3

15+6 = 33/3

21 = 11

No es cierta está igualdad

b. 96/[(4–2)(6)]=96/4–2(6)

96/[(2)(6)]=24–12

96/12=12

8=12

No es igualdad

c. 7–(12–9)=7–12+9

7–(3)=–5+9

4=4

Está igual es cierta

d. 29+[35/(–5)]=29+35/(–5)

29+[–7]=29+(–7)

22=22

Está igualdad es cierta
