Answer 1

Resposta:

a)25 b)81 c)343 d)100 e)100 f)243 h)121 i)441 j)1331 k)8000 i)2500

Explicação passo-a-passo:

a)(-5)^2= -5x-5=+25

b)(+3)^4=3x3x3x3=81

c)(-7)^2= -7x-7=49x7=343

d)-10^2=-10 x -10=100

e)(-10)^2=100

f)(-3)^5=243

h)(-11)^2= -11x-11=121

i)(-21)^2=441

j)(-11)^3=-11x-11=121 x11=1331

k)(-20)^3= -20x-20=400  x 20=8000

l)(+50)^2= 50x50=2500
