To apply the Zero Power Rule, we recognize that any non-zero number raised to the power of 0 is equal to 1. In your expression, \(1^0\) will equal 1 since 1 is a non-zero number.
Now we can rewrite the expression:
\[ 4/3(-2 + 1^0) = 4/3(-2 + 1) \]
So, the equivalent expression is:
\[ 4/3(-2 + 1) \]
In the blank, you would put 1:
An equivalent expression to \( \frac{4}{3}(-2 + 1^0) \) is \( \frac{4}{3}(-2 + \mathbf{1}) \).
