Answer 1

Resposta:

Explicação passo-a-passo:

A)

0,000000536 × 0,000002

= 5,36.10^(-7) . 2.10^(-6)

= 10,72.10^(-13)

= 1,072.10.10^(-13)

= 1,072.10^(-12)

_____________

B)

5,32.10⁷ + 3,75.10⁷ =

= 9,07.10⁷

5,32

3,75(+)

---------

9,07

-----------------

C)

= 0,000000000488 ÷ 4,22.10⁵

= 4,88.10^(-10) : 4,22 . 10^5

= 488/422 . 10^(-5)

= 1,156. 10^(-5)

----------------------

D)

2,99.10‐⁸ + 10, 67.10‐¹⁶

= 299.10^(-2).10^(-8) + 1067.10^(-2).10^(-16)

= 299.10^(-10) + 1067.10^(-18)

= 299.10^(-10)+ 0,00001067.10^8

10^(-18)

= 299.10^(-10) + 0,00001067.10^(-10)

= 299,00001067.10^(-10)

= 2,9900001067.10^2.10^(-10)

= 2,9900001067.10^(-8)

---------

E)

9,3.10⁸ × 7,12.10‐5=

= (9,3 × 7,12) . 10^(8-5)

= 66,216.10^3

= 6,6216.10.10^3

= 6,6216.10^4

---------------------

F)

= 9,44.10^(-5) – 6,19.10^(‐5)

= (9,44 –6,19) . 10^ (‐5)

= 3,25.10^(-5)

____________

G)

= 4,5.10³ ÷ 1,4.10‐⁴

= (4,5 ÷ 1,4) . 10^[3-(-4)]

= 45/14 . 10^7

= 3,75. 10^7

___________

H)

[(3.10³⁴ × 3.10^(‐10)] –5.10²⁴) +(2.10²⁴) =

= ( 9 . 10^(34-10) - 5.10^24 )+ 2.10^24

= 9.10^24 - 5.10^24 + 2.10^24

= 6.10^24
