Answer 1

86400

Step-by-step explanation:

If a number is in scientific notation, you simply move the decimal place to the right or left depending on the exponent on the 10.
In this case, the exponent is
4
. So we move the decimal 4 places to the right adding 0s when we need it. So we'll get
86400
