Correct answer: the first choice !
In order to write this in scientific notation, we must move the decimal from the beginning all the way to between the 5 and the 9
Note: you can move the decimal anywhere you want but typically scientific notation will have the decimal in between the first and second digit.
Since we move the decimal 24 digits to the right, our answer will be
5.972 * 10^24
or
5.972E24
Hope this helps!!
There's nothing to solve ._.
Since the absolute value makes numbers absolute or real numbers you could replace the ? with 8/9 or -8/9 since the negative will go away because of the absolute value sign.
