To determine the equivalent expression using the Zero Power Rule, we note that any non-zero number raised to the power of zero is equal to 1.
In the expression \( 7(-5.3)^0 + 4 \cdot 9 \):
- Identify \( (-5.3)^0 \): According to the Zero Power Rule, \( (-5.3)^0 = 1 \).
- Therefore, \( 7(-5.3)^0 = 7 \times 1 = 7 \).
- The entire expression simplifies to \( 7 + 4 \cdot 9 \).
Now calculate \( 4 \cdot 9 \):
\[ 4 \cdot 9 = 36 \]
So, we get:
\[ 7 + 36 = 43 \]
Now let’s examine the original responses available:
- \( 75.30 + 36 \)
- \( \frac{7}{5.3^0} + 36 \)
- \( 75.3 + 4 \cdot 9 \)
- \( 71 + 4 \cdot 9 \)
- \( 70 + 4 \cdot 9 \)
Among the responses, we note:
- \( 7 + 36 \) currently simplifies to \( 43 \).
Given these statements don’t offer a direct identifier for \( 43 \), we can see that it appears that \( 70 + 4 \times 9 \) also technically sums to \( 70 + 36 \), representing a combined approach towards the original values.
Finally, \( 70 + 36 \) does lead us to a derived sum.
Though identifying the expression format becomes complicated, the essence directs attention to:
The most direct response, mathematically treated, must be \( 70 + 4 \cdot 9 \) as it adheres to the Zero Power Rule in showcasing an addition structure similar to \( 43 \).
Thus, the simplest equivalent expression would be more categorically supported by identifying closely related forms.
Final conclusion: The best equivalent expression is \( 70 + 4 \cdot 9 \).
