Answer 1

Explicação passo-a-passo:

a) 35 +5²= 35 +25= 60

b) 50-4²= 50 - 16= 34

c) 2⁵ +0⁴ +2⁴= 32 + 0 +16= 48

d) 2⁴ -2² -2⁰= 16 - 4 - 1= 16 -5= 11

e) (-3)² +1 - 6⁰= +9 +1 - 1= 9

f) 2⁴ .2 .2³= 2⁴+¹+³= 2⁸

g) (-2)²= (-2).(-2)= +4

h) (-7)² + (+3)×(-4) - (-5)=

+49 + (-12 ) +5=

49 - 12 +5=

37 +5=

42

i) (-7)¹⁰ ÷ (-7)⁵= (-7)¹⁰-⁵= (-7)⁵

j) -2 + (-1) × (-3)²=

-2 + (-1) × (+9)=

-2 + ( - 9)=

-2 - 9=

-11
