How do you write 0.00643 in scientific notation?

Answer 1

#0.00643# in scientific notation is #6.43xx10^(-3)#

In scientific notation a number is written as #axx10^n#, where #n# is an integer and #a# is a number which has just one digit to the left of decimal i.e. #1<=a<10#.
Hence to write #0.00643# in scientific notation, we will have to move decimal three places to the right.
Hence #0.00643# in scientific notation is #6.43xx10^(-3)#

Answer 2

#6.43*10^5#

The key realization is that when we write numbers in scientific notation, we want one digit before the decimal point.

In our case, we must loop it #5# times to the left. The number of times we loop it is the exponent, and looping left makes it positive. Thus, we have
#6.43*10^5#

Hope this helps!

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.
