Could you explain operations with scientific notation using this example. 5 × 10³ + 4.3 × 10⁴ i dont understand how to solve it all . if you explain each step that would be great.

Explanation:

The scientific notation:

where

and k is integer.

We have the example:

You can write the numbers in a "normal" form:

Make the sum:

And next write it in the scientific notation:

You can add numbers in scientific notation if the power of tens in both number is the same.

Therefore you must convert the first number:

Now, you can make the sum:

um i think it might be a car?
