Hope this helps!
Answer:1
Step-by-step explanation:
Scientific notation is a number greater than 0 and less than 10 multiplied by 10 to a power. The expression will be equal to the number given.
91007500
We move the decimal place first so that the number is within our range:
9.1007500
Then we count how many places we moved the decimal. In this case we moved it to the left 7 times, so our exponent of 10 will be 7
Therefore in scientific notation it is 9.1007500 x 10^7
Some teachers prefer to have scientific notation rounded off to the nearest 10th place, so that would be:
9.1 x 10^7
Least precise to most precise: 21000 grams, 915 and 8.43 are the same precision, 5.426 seconds.
It looks alright to me but i would check it again see if you missed anything <span />
