Answer 1

Hello,
3x-1;
for x=1:
3(1)-1=3-1=2

Bye :-)

Answer 2

Answer: The required answer is 4.

Step-by-step explanation: We are given to evaluate the following expression for x = 1 :

`E(x)=2^(3x-1)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

To evaluate the given expression for x = 1, we must substitute x = 1 in equation (i).

From (i), we get

`E(1)=2^(3*1-1)=2^2=4.`

Thus, the required answer is 4.
