Realize as seguintes operações:

a) 10^3 × 10^4 × 10^2 =

b) 10^-3 × 10^4 ×10^-2 =

c) 10^-4 × 10^-6 × 10^4 × 10^3 =

d) 10^-5 : 10^4 =

e) 10^6 : 10-1 =

f) 10^4 : 10^4 =

Answer 1

a)1.000.000.000
b)0.1
c)0.001
d)1e-9
e)10.000.000
f)1

Answer 2

a)10^3 x 10^4 x 10^2=
(1,000 x 10,000 ) x 100=
10,000,000 x100=
=1,000,000,000

b)10^-3 x 10^4 x 10^-2=
(0,001 x 10,000) x 0,01=
10 x 0,01=
=0,1

c)10^-4 x 10^-6 x 10^4 x 10^3=
(0,0001 x 0,000001) x (10,000 x 1000)=
0,0000000001 x 10,000.000=
=0,001

d)10^-5 / 10^4 =
0,00001/10,000=
=0,000000001 ou  1E-9

e)10^6 / 10^1 =
1.000,000 / 10 =
=100,000

f) 10^4 / 10^4=
10,000 / 10,000=
=1
 Espero ter ajudado !
