0.007 is 1\10 of what because i don't make sense

0.007 x 10 = 0.07

In the scientific value of 5.893 x 10n. The standard value is 0.00005893 what is n? To better illustrate this phenomenon, we can explain it further under the rules of scientific notation. 
For example. 
1.  3 x 10^3 = 3 x 100 = 300 
2.  3 x 10^-3 = 3 x 0.001 = 0.003 

Solution: 
0.00005893 = 5.893 x 0.00001 = 5.893 x 10^-5   
n= ^-5

If i'm correct the answer is $15.97
