Question

Alguien me puede alludar ​

Answer 1

a) 7 • (2 + 3)
= 7 • 5
= 35

b) -6 - 3 + 10 - 7(3 + 2)
= -6 - 3 + 10 - 7(5)
= -6 - 3 + 10 - 35
= (-6 - 3 - 35) + 10
= -44 + 10
= -34

C) 8 - (6 + 7 - 3)
= 8 - (13 - 3)
= 8 - (10)
= 8 - 10
= -2

D) (6 - 15) - [7(3 + 4) - 1]
= (-9) - [7(7) -1]
= -9 - [49 - 1]
= -9 - [48]
= -9 - 48
= - 57

E) 13 - _/64 • [7^2(3 - 6) + 2]
= 13 - _/64 • [7^2(-3) + 2]
= 13 - _/64 • [49(-3) + 2]
= 13 - _/64 • [-147 + 2]
= 13 - _/64 • -145
= 13 - 8 • -145
= 13 - (8 • -145)
= 13 - (-1160)
= 13 + 1160
= 1173

F) 24 + 120 : 4 - [11(12 - 2)]
= 24 + 120 : 4 - [11(10)]
= 24 + 120 : 4 - [110]
= 24 + 120 : 4 - 110
= 24 + 30 - 110
= (24 + 30) - 110
= 54 - 110
= -56

G) {37 -[10 -(2-6)+20]+2}•4^4
= {37 - [10 - (-4) + 20] + 2} • 4^4
= {37 - [10 + 4 + 20] + 2} • 4^4
= {37 - 34 + 2} • 4^4
= {(37 + 2) - 34} • 4^4
= {39 - 34} • 4^4
= 5 • 4^4
= 5 • 256
= 1280

H) 15•[9-(-7)]-28:[12-(-10)]+15•[20+(-4)]+38
= 15•[9+7]-28:[12+10]+15•[20-4]+38
= 15 • 16 - 28 : 22 + 15 • 16 + 38
= 240 - 1,2727 + 240 + 38
= (240 + 240 + 38) - 1,2727
= 518 - 1,2727
= 516,7272

I) 3_/64•[12^2-(7^2-6^2)]:[_/144+(_/121-5)]
= 3_/64•[12^2-(49-36)]:[_/144+(11-5)]
= 3_/64 • [12^2 - (13)] : [_/144 + (6)]
= 3_/64 • [144 - 13] : [12 + 6]
= 3_/64 • 131 : 6
= (4 • 131) : 6
= 524 : 6
= 87,333
