The answer is C. 5.000039x10^6.
In order to change something into scientific notation you have to move the decimal place enough times to get the first number to be between 1 and 9. After that, you must count how many space you moved it and that is your exponent. Moving the decimal space to the left gives you a positive exponent. Moving it to the right gives you a negative exponent.
It means break them down so u get just one factor
I believe the answer is x⁢10 if it’s incorrect i’m so sorry
Both 38 and 58 are even so they both can be divided by 2,
38/58
19/29
that is in the simplest form
