which of the following is an equivalent expression to 7/(-5.3)^0 +4 ∙ 9 when apply the zero power rule.
A. 7/5.3 +4 ∙ 9
B. 7/0+4∙9
C. 7/5.3^0 +36
D. 7/1+4∙9
The zero power rule states that any number (except zero) raised to the power of zero is equal to 1. Therefore, when we apply the zero power rule to (-5.3)^0, we get 1.
So, the expression 7/(-5.3)^0 + 4 ∙ 9 can be simplified to 7/1 + 4 ∙ 9.
The equivalent expression to 7/(-5.3)^0 + 4 ∙ 9 when applying the zero power rule is:
D. 7/1 + 4 ∙ 9.
