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).
