76,994 = 76994.

there is an invisable point at the end of any whole number.

you have to jump it over the 4 the 9 the 9 and the 6  SO that it ends up between the 7 and the 6.    That is 4 jumps.   So the power is 4

 

$$76994=7.6994\times 10^4$$

 

This might be displayed on a calc as     7.6994E4

None. 7.6994 E4 should be correct.

After review I see that the misinterpretation was due to a missing ^ after the 10 of each number.  My apologies.
