Answer:

#4.85*10^-5#

Explanation:

you take that number and count how far away the first digit is from #0#. The #8# is five digits away from the zero after the decimal.

The five will be the exponent, but since the non-zero digits are to the right of the zeroes, it'll be #-5#. We're basically looping the decimal 5 times to the right, which means the exponent will be negative.

#=>4.85*10^-5#

Answer:

#4.85*10^-5#

Explanation:

When we write numbers in scientific notation, we want the decimal after the first non-zero digit.

In our case, we want the decimal between the #4# and the #8#. This means we have to loop the decimal five times to the right.

The #5# will be our exponent, but since we looped it right, it'll be negative. Thus, we have:

#4.85*10^-5#

Hope this helps!
