give me some math problems that relate to subtracting numbers in scientific notation

Here are some math problems that involve subtracting numbers in scientific notation:

### 1.  
Subtract the following numbers written in scientific notation:
\[
(6.4 \times 10^5) - (3.1 \times 10^5)
\]

### 2.  
Subtract the numbers below:
\[
(8.5 \times 10^7) - (4.2 \times 10^7)
\]

### 3.  
Subtract these two values in scientific notation:
\[
(9.6 \times 10^3) - (2.3 \times 10^3)
\]

### 4.  
Find the difference between these two numbers:
\[
(5.0 \times 10^9) - (1.7 \times 10^8)
\]

### 5.
