iv. 4



Please give my answer
​

Answer 1

Explanation:

x=2

$(3 ^{2x - 1} - 5) \div 2= 11 \\ 3 ^{2x - 1} - 5 = 22 \\ {3}^{2x - 1} = 27 \\ 2x - 1 = 3 \\ x = 2$

Answer 2

Answer:

x=2

\begin{gathered}(3 ^{2x - 1} - 5) \div 2= 11 \\ 3 ^{2x - 1} - 5 = 22 \\ {3}^{2x - 1} = 27 \\ 2x - 1 = 3 \\ x = 2\end{gathered}(32x−1−5)÷2=1132x−1−5=2232x−1=272x−1=3x=2
