Count the number of digits after the first digit. this gives you the exponent on the 10. The first number in scientific form has the decimal point after the first digit.
For mercury there are 7 digits after the 5:-
So the Mercury answer is
5.7909175 * 10^7
Follow this procedure for the other planets
The answer for Venus is
1.08208930 * 10^8
Okay so in school I am doing this litterly right now. So all u have to do is when it is a different sign you subtract, when it is the same you add. So think of it as, Different/Difference and Same/Sum. when the sign is different u find the difference and when u have the same sign you find the sum.
Example 1: -3+8= 5
Use the same sign as the largest number
Example 2: 5+(-10)= -5
Hopefully This helped! It is easier then you may think once you get the hang of it! ( You get the hang of it REALLY fast ) :)
