Question 624778
Place the decimal point between the first two digits to get 7.6485


Now move the decimal 4 places to the right (to get back to the original number). 


So the base is <font color="red">7.6485</font> and the exponent is <font color="blue">4</font>



This means that 


76,485 = <font color="red">7.6485</font> x 10^<font color="blue">4</font>
