    X

    3^x+3^(x+1)=3^2+3^2

    How would I calculate x?

    Solve the right, substitute for X so that left = right.

    You need to clarify your equation more before we can understand what it's asking.

    Cool
    3x+3(x+1)= 32+32 =>
    3x+x+1 = 32+2 =>
    32x+1 = 34

    I don't know how to go further...

    Take the natural log of both sides then solve for x.

    You mean like this?

    2x+1=4 => 2x=4-1 => 2x=3 => x=1.5

    Then I would go back to the equasion and put the "x" into it:

    32(1.5) + 1 = 34
    33+1 = 34
    34 = 34

    I don't know how to go further...
    32 + 32 = 9 + 9 = 18
    32+2 = 81

    But the question is: 3x+3x+1=32+32. What is x?
    I can't seem to figure it out.

    @iverson954360, halp please
