Write down the following in exponential form:
`4xx 2 xx x xx x xx x xx y xx y xx z`

Answer

To write the expression `4 xx 2 xx x xx x xx x xx y xx y xx z` in exponential form, we can follow these steps:

### Step 1: Identify the constants and variables
The expression consists of:
- Constants: 4 and 2
- Variables: x, y, z

### Step 2: Multiply the constants
First, we multiply the constants:
\[ 4 \times 2 = 8 \]

### Step 3: Count the occurrences of each variable
Next, we count how many times each variable appears:
- For \( x \): It appears 3 times (x xx x xx x).
- For \( y \): It appears 2 times (y xx y).
- For \( z \): It appears 1 time (z).

### Step 4: Write the variables in exponential form
Now we can write the variables in exponential form:
- \( x \) appears 3 times, so we write it as \( x^3 \).
- \( y \) appears 2 times, so we write it as \( y^2 \).
- \( z \) appears 1 time, so we write it as \( z^1 \) (but we can simply write \( z \) since \( z^1 = z \)).

### Step 5: Combine everything into the final expression
Now we can combine everything:
\[ 8 \times x^3 \times y^2 \times z \]

### Final Answer
The expression in exponential form is:
\[ 8x^3y^2z \]
