Alborosie

Answer:

First option is correct. The solution of the equation is x=1.

Step-by-step explanation:

The given equation is

\frac{1}{2}x+\frac{3}{2}=2^x

The value of x, which satisfy the above equation is the solution of the given equation.

Put x=1 in the given equation.

\frac{1}{2}(1)+\frac{3}{2}=2^{1}

\frac{1+3}{2}=2

\frac{4}{2}=2

2=2

Since left hand side is equal to right side, therefore first option is correct.

Put x=2 in the given equation.

\frac{1}{2}(2)+\frac{3}{2}=2^{2}

\frac{2+3}{2}=4

\frac{5}{2}=4

Since left hand side is not equal to right side, therefore second option is correct.

Put x=4 in the given equation.

\frac{1}{2}(4)+\frac{3}{2}=2^{4}

\frac{4+3}{2}=16

\frac{7}{2}=16

Since left hand side is not equal to right side, therefore third option is correct.

Put x=8 in the given equation.

\frac{1}{2}(8)+\frac{3}{2}=2^{8}

\frac{8+3}{2}=256

\frac{11}{2}=256

Since left hand side is not equal to right side, therefore fourth option is correct.
