You can put this solution on YOUR website! Count how many "jumps" are needed to take the decimal from its current location to right after the 1st number that's not zero (which is 2). In this case the decimal moves 7 spots to the right to get 2.4. To write in scientific notation you need to write it as
This is written as such to get back to 0.00000024. You have to multiply 2.4 by a really small number to get a small number (anything to a negative power is a fraction. Eg )
You can put this solution on YOUR website! REMEMBER THAT IN SCIENTIFIC NOTATION YOU ARE TRYING TO EXPRESS YOUR VALUE AS THE LOWEST NUMBER, TIMES YOUR BASE TEN VALUE. IN YOUR PROBLEM, YOU NEED TO MOVE THE DECIMAL POINT SEVEN PLACES TO THE RIGHT >>>>>>> THEN YOU HAVE 2.4 >>>>> WHAT ABOUT YOUR BASE 10 VALUE? SINCE YOU MOVED THE DECIMAL TO THE RIGHT YOU ALWAYS HAVE A NEGATIVE BASE TEN VALUE - IF YOU MOVE YOUR DECIMAL TO THE LEFT YOU HAVE A POSITIVE BASE TEN VALUE. IN YOUR PROBLEM , WE MOVED THE DECIMAL SEVEN PLACES TO THE RIGHT, THEREFORE, 10^-7 >>>>> YOUR ANSWER IS >>>>>>>>>> 2.7 X 10^-7 >>>>>>> I HOPE THIS HELPS YOU!?
