Answer:

#5.16xx10^-5#

Explanation:

See how many #0's# there are until you get to the number between #1-10# (in this case #5.16)#, it takes 5 steps from the decimal point.

#-> 5.16xx10^-5# as this is #0.0000516# not #516000#, you use a negative power.

Answer:

#5.16xx10^-5#

Explanation:

Whenever you move the decimal point #color(blue)(back)# you multiply it with a #color(blue)(10^-n)#; and when you move the decimal point #color(red)(f)color(red)(ront)# then you multiply it with #color(red)(10^n)# where #n# is the number of time you moved the decimal point.
Since, this is the first case, you move the decimal point #5# places back and multiply it with #10^-5#.

Hope this helps :)
