Answer and Step-by-step explanation:
Alot of these can be solved with the table up above the problems.
<h2>A, B, and C.</h2><h2></h2>
According to the table, every time a value has an exponent of 0, it would equal to 1. Since all A B and C values follow the 0 exponent, their value is 1.
<h2>D.</h2><h2 />
According to the table, when we have a negative exponent, the number gets turned into a fraction of
Since our value is 9^-2, do as followed :
Solve what is 9^2 :
This question is different, since we have to go backwards, we have to switch the negative exponent to a positive exponent and rid the fraction.
Since we have one negative exponent, follow the fraction rule but instead of having one as the numerator, have 5a^3.
Since -3 is in parenthesis, we can rid the negative along with the parenthesis :
Follow the negative exponent rule :
Follow the negative exponent rule yet again :
