3^(x^2)=1
log3(x^2)=log1
x^2log3=log1
x^2=log1/log3
x^2=o
x= square root of 0
x=o

3^(x^2)=1

x^2=log1/log3
x^2=0
x= square root of 0
x=0
---------------
check the answer.
(3^(x^2)) + 5 = 6
3^0 + 5 = 6
1 + 5 = 6
6 = 6 Must be right.

If that is the correct equation, then you have the right answer.
Check:
Start with the given equation.
Plug in
Square 0 to get 0
Raise 3 to the zeroth power to get 1
Add. Since the equation is true, this verifies the answer
So either the book has the wrong answer or there's a typo in the problem.
