Solve 2x − 1 = 11 for x using the change of base formula log base b of y equals log y over log b.

I think your equation is

Step-by-step explanation:

To solve the equation take natural log on both sides of equation:

        (∵   )

(remember and are same)

using base changing property:

      (∵ )

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
