Responses
71+4⋅9
Start Fraction 7 over 1 End Fraction plus 4 times 9
75.3+4⋅9
Start Fraction 7 over 5.3 End Fraction plus 4 times 9
75.30+36
Start Fraction 7 over 5.3 superscript 0 baseline End Fraction plus 36
70+4⋅9
The expression 7(−5.3)0+4⋅9 is already simplified and does not require the Zero Power Rule. Therefore, none of the given expressions are equivalent.
To apply the Zero Power Rule, any number raised to the power of 0 becomes 1.
In the given expression, 7(−5.3)0 + 4⋅9, the term (-5.3)^0 will become 1.
So, an equivalent expression to 7(−5.3)0 + 4⋅9, when applying the Zero Power Rule, is:
71 + 4⋅9.
