The first step for solving this expression is to write the number below ㏒ in exponential form.
㏒
(x) + 2㏒
(y) - ㏒
(z)
Using ㏒
(b) =
× ㏒
(b),, transform the expressions with ㏒
.
× ㏒
(x) +
× ㏒
(y) - ㏒
(z)
Lastly,, reduce the numbers with 2 to find your final answer.
× ㏒
(x) + ㏒
(y) - ㏒
(z)
This means that the correct answer to your question is
× ㏒
(x) + ㏒
(y) - ㏒
(z).

Answer:
C.47
Step-by-step explanation:
You want to plug in all the numbers which gives you 3^3+2(8)- -4. You do 3*3*3 which gives you 27. You then do 2(8) which gives you 16. So your problem now is 27+16- -4. 27+16 is 43 and being you are subtracting a negative, it turns to a positive. So your answer ends up being 47.
