To solve the expression \( 6.9 - 2^0 \), we first need to evaluate \( 2^0 \).

Recall that any non-zero number raised to the power of 0 is equal to 1. Therefore,

\[ 2^0 = 1 \]

Now we can substitute this back into the expression:

\[ 6.9 - 2^0 = 6.9 - 1 \]

Subtracting 1 from 6.9 gives us:

\[ 6.9 - 1 = 5.9 \]

So the value of \( 6.9 - 2^0 \) is 5.9.
