Question

Efetue as operações indicadas:

A)10^2 . 10^5 =
B)10^15 . 10^-11 =
C)2.10^-6 . 4.10^-6 =
D)10^10 : 10^4 =
E)10^15 : 10^-11 =
F)4,8.10^-3 : 1,2.10^4 =

Answer 1

A)

= 10^2 . 10^5

= 10^(2+5)

= 10^7

B)

= 10^15 . 10^-11

= 10^(15-11)

= 10^4

C)

= 2.10^-6 . 4.10^-6

= 8.10^(-6)

D)

= 10^10 : 10^4

= 10^(10-4)

= 10^6

E)

= 10^15 : 10^-11

= 10^[15 -(-11)]

= 10^26

F)

= 4,8.10^-3 : 1,2.10^4

= 4.10^(-3-4)

= 4.10^(-7)

d) 10^10 : 10^4

10^(10-4)

10^6

e) 10^15 : 10^-11

10^[15 -(-11)]

10^26

f) 4,8.10^-3 : 1,2.10^4

4.10^(-3-4)

4.10^(-7)
