Question

represente os proximos numeros em notaçao cientifica :

a)19.876.863 X 10-3 

b ) 57.670.000 X 10-3

c)7.896,10 X10-2 

d_ 0 , 017896 X 10 -9

Answer 1

$<var>a)19.876.863 \cdot 10^{-3} = 1,9876863 \cdot 10^4</var>$ 

$<var>b ) 57.670.000 \cdot 10^{-3}=5,767 \cdot 10^4</var>$

$<var>c)7.896,10 \cdot10^{-2} = 7,8961 \cdot 10</var>$

$<var>d) 0 , 017896 \cdot 10 ^{-9}=0,17896 \cdot 10^{10}</var>$

Answer 2

 

a)19.876.863 X 10-3 = 1,9876863.10^7.10^-3 = 1,9876863.10^4

 

b ) 57.670.000 X 10-3 = 5,767.10^7.10^-3 = 5,767.10^4

 

c)7.896,10 X10-2  = 7,89610.10^3.10^-2 =  7,898610.10 

 

d_ 0 , 017896 X 10 -9 = 0,1786.10^-10
