When you add numbers in scientific notation, it is best to convert them to their original decimal form, or at least change them so that they have the same exponent. Then when you are finished adding, simply put the solution is proper scientific notation.

the exponents have to be the same, so you have to change one of the numbers (using lars) to be able to solve the equation
You add exponents when multiplying. Ex: (xm) × (xn) = xm+n
How to write them? ten to the minus three is 10^-3How to multiply them? add the exponents. Ex: 10^-3 x 10^-4 = 10^-7
You have to add the exponents. It's best if you just remember it. You can also consider what happens when you multiply something like:(2 x 2 x 2) x (2 x 2) As you can notice, the number of factors get added. That's like adding the exponents.
If you are multiplying numbers with exponents, and the base is the same, you can just add exponents. For example, 104 x 105 = 109.
To write 67.5 billion in scientific notation, we first need to move the decimal point to the right so that there is only one non-zero digit to the left of the decimal point. In this case, we would move the decimal point 10 places to the right, resulting in 6.75. Next, we express this number as a product of a number between 1 and 10 and a power of 10. Therefore, 67.5 billion in scientific notation is 6.75 x 10^10.
