Match the numbers on the left with their equivalent expressions written in scientific notation on the right. you may wish to watch the videos powers of 10, parts 1 and 2, before you begin.

The question is incomplete. I'll give a general method on how to solve questions like this..

Step-by-step explanation:

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

It is used because it makes it easier when dealing with very big or very small numbers.

Take for example, 43000000 could be written as 4.3 * 10^7 or 4.3E7.

To figure out the power of 10, think "how many places do I move the decimal point?"

When the number is 10 or greater, the decimal point has to move to the left, and the power of 10 is positive.

When the number is smaller than 1, the decimal point has to move to the right, so the power of 10 is negative.

Now let's solve the following.

1. 68000 = 6.8*10^4 or 6.8E4

2. 0.0000007 = 7*10^-7 or 7E-7

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
