A typical snake bite delivers 0.0045 grams of venom.
Maria wrote it in scientific notation as
Tammy wrote it in scientific notation as
Any number can be written in the form of scientific notation as follows :
(a is real no and b is integer)
The given no is 0.0045.
There are 2 zeroes before 4. Also the decimal is there before 2 zeroes.
Hence, Maria is correct.
Question 1:

Personally I prefer the zero up front to make the decimal point stand out easier. Of course it's just a preference, so its up to you to decide which you prefer.

Question 2:
<h3>Answer: Yes the number changes</h3>Taking the zero out of 10.25 leads to 1.25 which is definitely a different number (and smaller). Therefore, this zero is a significant digit compared to before.
