evaluate the following for x
You must mean "solve the following for x" ? If yes, then :

log(2x) = \frac{\ 1}{7}
2x = 10^{\frac{\ 1}{7}}
x = \frac{\ 10^{\frac{\ 1}{7}}}{2}

(a + b)(a + b + c)
a(a + b + c) + b(a + b + c)
a^2 + ab + ac + ba + b^2 + bc
a^2 + b^2 + 2ab + ac + bc

But maybe I don't understand what you wrote, try using the LaTeX editor ?
