11) The average distance of the Moon from the Earth is 386,242,560 m . Represent this value in scientific notation.

To represent the value $$386,242,560$$ in scientific notation, we need to express it as a product of a number between 1 and 10 and a power of 10.

First, identify the significant figures in the number:
$$386,242,560$$

Next, place the decimal point after the first non-zero digit:
$$3.86242560$$

Now, count the number of places the decimal point has moved from its original position to its new position:
$$386,242,560 \rightarrow 3.86242560$$
The decimal point moves 8 places to the left.

Therefore, the number in scientific notation is:
$$3.86242560 \times 10^8$$

So, the average distance of the Moon from the Earth in scientific notation is:
$$3.86242560 \times 10^8 \, \text{m}$$
