Answer: The required answer is 4.
Step-by-step explanation: We are given to evaluate the following expression for x = 1 :
[tex]E(x)=2^{3x-1}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To evaluate the given expression for x = 1, we must substitute x = 1 in equation (i).
From (i), we get
[tex]E(1)=2^{3\times1-1}=2^2=4.[/tex]
Thus, the required answer is 4.
