Answer:

Option 1 -
\log_a (3c-d)=2b+1

Explanation:

Given : Equation
a^(2b+1)=3c-d

To find : Which of the following is the equation ?

Solution :

Equation
a^(2b+1)=3c-d

Taking log both side,


\log (a^(2b+1))=\log (3c-d)

Apply logarithmic property,
\log a^x=x\log a


(2b+1)\log (a)=\log (3c-d)


(2b+1)=(\log (3c-d))/(\log a)

Apply change the base rule,
(\log _a x)/(\log _a y)=\log_y x


(2b+1)=\log_a (3c-d)

So, the required equation is
\log_a (3c-d)=2b+1

Therefore, option 1 is correct.
