Answer 1

Resposta:

1- a) 3x9+50-20+15-120/2= 27+30+15-60= 57-45= 12

b) 4x(5+20)-45+8×2= 100-45+16= 39

c) 16+[14+(22×3)-72]= 16+[14+66-72]= 16+8= 24

d) 140-{25×3[50×2(70/7)+24]+12}= 140-{75+[100+10+24]+12}= 140-{75+134+12}= 140-221= -81

e) 3⁴+22-6×4+250-240/10= 81+22-24+250-24= 101+202= 303

f) 320+5×(10+3-20)+55/5-47= 325×(-7)+11-47= -2.275-36= -2.311

2- a) 2³= 2×2×2= 8

b) 4²= 4×4= 16

c) (-2)²= (-2)×(-2)= 4

d) 10²= 10×10= 100

e) 5⁴= 5×5×5×5= 625

f) 7²= 7×7= 49

g) (-3)³= (-3)×(-3)×(-3)= -27

3- a) (-2)⁵= (-2)×(-2)×(-2)×(-2)×(-2)= -32

b) (-7)²= (-7)×(-7)= 49

c) (-3)⁵= (-3)×(-3)×(-3)×(-3)×(-3)= -243

d) (-10)³= (-10)×(-10)×(-10)= -1000

e) (-1)⁵= (-1)×(-1)×(-1)×(-1)×(-1)= -1

f) (-6)⁴= (-6)×(-6)×(-6)×(-6)= 1296
