(3 to the power of 0 + 7
to the power of −1 − 8 to the power of 
0)
entirely to the power of −1

Let's break down the expression step by step:

\[
\left( 3^0 + 7^{-1} - 8^0 \right)^{-1}
\]

### Step 1: Simplify individual terms inside the parentheses.

1. \( 3^0 = 1 \) (Any non-zero number to the power of 0 is 1).
2. \( 7^{-1} = \frac{1}{7} \) (Any number raised to the power of -1 is the reciprocal of that number).
3. \( 8^0 = 1 \) (Again, any non-zero number to the power of 0 is 1).

Now substitute these values into the expression:

\[
\left( 1 + \frac{1}{7} - 1 \right)^{-1}
\]

### Step 2: Simplify the expression inside the parentheses.

\[
1 + \frac{1}{7} - 1 = \frac{1}{7}
\]

### Step 3: Apply the exponent of -1 to the result.

\[
\left( \frac{1}{7} \right)^{-1} = 7
\]

### Final Answer:

\[
7
\]
