Answer:
[tex]8.4\times10^5[/tex]
Step-by-step explanation:
In order to turn a scientific notation into standard form you must move the decimal point as many times as the exponent depending on if the exponent is a negative or a positive. (negative goes to the left, positive goes to the right)
[tex]8.4\times10^5[/tex]
The exponent is positive therefore the decimal point goes to the right:
[tex]8.,4,0,0,0,0[/tex]
[tex]=840000[/tex]
Hope this helps.
