Question

Responses

70+4⋅9
Start Fraction 7 over 0 End Fraction plus 4 times 9

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

Answer 1

To apply the Zero Power Rule, any number raised to the power of zero is equal to 1.

Therefore, an equivalent expression to 7(-5.3)^0 + 4⋅9 is:

7(1) + 4⋅9

Which simplifies to:

7 + 36

So the correct answer is:

71+4⋅9
