need the solution for this question..

5 power x square - 5 power 2(6x-2)=0
5 power x square + 5 power 2(6x-2)=0

[Wong Tok Hua]

5^(x^2) -5^2(6x-2) = 0
5^(x^2) = 5^2(6x-2)
So, x^2=12x-4
and solve this quadratic equation, you will get the answer.

5^(x^2) + 5^2(6x-2) = 0
Now, 5^(x^2) > 0 and 5^2(6x-2) > 0
Therefore, no real solution for this equation.
