Answer:

y=0

Explanation:

Rewrite Evaluate Powers:

3
3^(2y-1)+3^(-1)+2*3^(y)*3^(-1)=1

Calculate:


(3^(y))^(2)*(1)/(3) +2*3^(y)*(1)/(3)=1

Solve using substitution:


(3^(y))^(2)*(1)/(3) +(2)/(3) *3^(y)=1
t=3^(y)

Solve the equation for t:


t^(2)*(1)/(3)+(2)/(3)t=1

t=-3

t=1

Substitute back to t=3^y

3^y=-3

3^y=1

y∉R


3^(y)=1

y=0
