What is the equivalent exponential expression for the radical expression below?
√2 +6
A. (2 + 6)^1/2
B. 82
C. 8
D. (2 + 6)^2

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.

both equations and proportions are better.

-6 is the correct option from the above given options
