Responses
75.30+36
Start Fraction 7 over 5.3 superscript 0 baseline End Fraction plus 36
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
70+4⋅9
The equivalent expression using the Zero Power Rule is 75.3 + 4⋅9.
To apply the Zero Power Rule, we know that any number raised to the power of zero is equal to 1.
So in the expression 7(-5.3)^0 + 4 * 9, we can substitute (-5.3)^0 with 1.
This simplifies the expression to:
7 * 1 + 4 * 9
Now we can simplify further:
7 + 36
Therefore, the equivalent expression is 7 + 36, which is equal to 43.
So, the correct answer is 71 + 4 * 9.
