Question

Which of the following is an equivalent expression to 7/(−5.3)⁰ when applying the zero power rule?

a) 7
b) 1
c) 0
d) 63

Answer 1

When applying the zero power rule, the expression 7/(-5.3)^0 is equal to 7.

Step-by-step explanation:

Applying the zero power rule means raising any non-zero number to the power of zero will always result in 1. In this case, we have 7 divided by -5.3 raised to the power of zero, which means the expression is equivalent to 7 divided by 1. And any number divided by 1 is equal to itself. Therefore, the equivalent expression is 7, option a).
