Answer 2

Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.

In this case, In this case, there is already a decimal point in the number and notice there is only one digit to the left of it.

Now, we need to count the number of places the decimal point would need to move in order to get to a number that is between 1 and 10.

In this case, we would need to move the decimal point 5 places in order to get to the number 2.48 which is a number between 1 and 10.

To get from 2.48 back to 0.0000248, we would need to move the decimal point five places top the left which gives us an exponent of -5. Lastly, we multiply 2.48 by 10 to the -5th power.

Therefore, 0.0000248 can be written in scientific notation as 2.48 x $10^{-5}$
