Final Answer:
b) 1 because according to the zero power rule in mathematics, any non-zero number raised to the power of zero equals 1. In the given expression, 7 multiplied by (-5.3) raised to the power of 0 and 4 multiplied by 9 remain unchanged.
Step-by-step explanation:
When dealing with the zero power rule, it's important to understand that any non-zero number raised to the power of zero equals 1. In this equation, the expression 7 multiplied by (-5.3) raised to the power of 0 becomes 7 times 1, and the term 4 multiplied by 9 remains unchanged.
Thus, simplifying the expression results in 7 times 1 times 36, which simplifies further to 1 times 36, giving us the value of 36.
Therefore, despite the initial appearance, the equivalent expression actually evaluates to 36, aligning with the principle that any non-zero number raised to the power of zero yields 1.
Hemce, option b) is correct.
