Let’s multiply and divide numbers written in scientific notation.
Now, let’s move on to multiplying numbers written in scientific notation.
Here’s an example
Everything here should be multiplied
Let’s break it down to
Let’s group the like terms first then multiply
may look like a scientific notation but it’s not.
Remember, should be greater than or equal to and less than .
So let’s simplify it further by moving one decimal space to the left.
We now have
Let’s have two more examples.
Let’s multiply now is
So now we have
We don’t have to make any adjustment because it is already in scientific notation form.
Let’s try this one
So we have
Then let’s move the decimal to get a value between and .
The answer is
Now, let’s do division of numbers written in scientific notation.
Let’s divide the like terms
So our answer is
Let’s have a more difficult one
Let’s do this
But this is not a scientific notation.
To write it down, we have to move the decimal space.
The final answer should be
