What is the difference written in scientific notation 1.3x10^6 - 6.8 x 10^5

Answers

Answer from: zstarr

One way to solve this is to revert to integers.

Do this by moving the decimal in 1.3 to the right 6 places (indicated by the positive power value) and then 6.8 move the decimal to the right 5 places (same reason)

Now you have 1,300,000 & 680000. Subtract to get 620,000.

Now convert your product to scientific notation again by moving your decimal to the left until you are left with 6.2 x ? The question mark will be 10 to the number of places you moved the decimal. 10^5

We have 6.2 x 10^5.

It is import to note that when the decimal must be moved to the right for values less than one, the power will be negative.
