5^15

Step-by-step explanation:

Multiply the exponent that is inside the parentheses (3) by the exponent on the outside (9) to get 27 for the exponent, then subtract the exponent that is divided (12) to get an exponent of 15, which makes the answer 5^15.

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.
