Accepted Answer

### 1st Blank:
# Brief Explanations:
Scientific notation is designed for very large or very small numbers (like $0.00005$ or $5000000$) to make them easier to handle.
# Answer:
small

### 2nd Blank:
# Brief Explanations:
In scientific notation, the standard form is $a\times10^{n}$ where $1\leq|a|\lt10$ and $n$ is an integer, so it's a power of 10.
# Answer:
10

### 3rd Blank:
# Brief Explanations:
In $a\times10^{n}$, the exponent $n$ dictates the number of places the decimal moves. For example, in $5\times10^{3}$, the exponent 3 means moving the decimal 3 places right.
# Answer:
exponent

### 4th Blank:
# Brief Explanations:
A positive exponent (e.g., $10^{3}$) in $a\times10^{n}$ means we move the decimal to the right (e.g., $5\times10^{3}=5000$, decimal moves 3 right from 5.0).
# Answer:
right

### 5th Blank:
# Brief Explanations:
A negative exponent (e.g., $10^{-2}$) in $a\times10^{n}$ means moving the decimal to the left (e.g., $5\times10^{-2}=0.05$, decimal moves 2 left from 5.0).
# Answer:
left

### 6th Blank:
# Brief Explanations:
For $4.5\times10^{-2}$, the negative exponent $-2$ means we move the decimal 2 places to the left (since negative exponent indicates left movement). So $4.5\times10^{-2}=0.045$, moving decimal 2 left from 4.5.
# Answer:
left
