write 900,000 in scientific notation

Sagot :

[tex]900,000=9\cdot10^5[/tex]
900,000.
move the decimal so that your number is between 1 and 10
9.00000
count how many spaces the decimal moved (5)
then take your new number (9) and multiply by 10 to the power of 5 because that was the distance the decimal moved
9 x 10^5
