#5 xx 10^7#

Scientific form uses powers of ten to write very large or very small numbers quickly, easily, and accurately.

Before the decimal point, there can be only ONE non-zero digit.

Count the number of places you have moved the decimal point from its position at the end of the number to after the 5. (Each is another power of 10)

Another approach in this case would be to read it in words as 50 million. 50 is #5 xx 10^1# and one million is #1 xx 10^6#

#(5 xx 10^1) xx (1 xx 10^6) = 5 xx 10^7#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
