Question

Escreva as potências de dez na forma usual:
a) 6x10^4

b) 1,2x10^-6

c) 4,9x10^2

d) 2,66x10^3

e) 6,21x10^-1

Answer 1

Escreva as potências de dez na forma usual:
a) 6x10^4

6.10⁴
6.(10x10x10x10 =  
6.(10.000) = 60.000 

b) 1,2x10^-6
1,2 .10⁻⁶
1.2.(1/10⁶)
1,2.(1/1.000.000)
1,2(0,000 001) =
0,000012

c) 4,9x10^2
4,9.10²
4,9.(10x10)
4,9.(100) = 490


d) 2,66x10^3

2,66.10³
2,66.(10x10x10)
2,66(1000) = 2.660



e) 6,21x10^-1

6,21.10⁻¹
6,21.(1/10¹)
6,21.(1/10)
6,21.(0,1) = 0,621
