Answer 1

Explicação passo-a-passo:

a)(-9)^2-(+5).(+16)=

81-80

1

b)(-2)^4:(+16).(-1)^7=

16:(+16).(-1)=

1.(-1)=

-1

c)(-6)^2-(-7)^2+13^0=

36-49+1=

-13+1=

-12

d)5^2-(-3)^3+(-4)^2=

25-(-27)+16=

52+16=

68

e)4.(-5)^3+(-20)^2=

4.(-125)+400=

-500+400=

-100

f)11^2-4.(-5)^2+10^0=

121-4.25+1=

121-100+1=

21+1=

22

g)17-3.(-2)^2-(-6)^2.(-1)^7=

17-3.4-36.(-1)=

17-12-(-36)=

17-48=

-31

h)7.(-2)^2-5.(-2)^3-10^2=

7.4-5.(-8)-100=

28-(-40)-100=

68-100=

-32
