Assuming all variables are positive, use properties of logarithms to write the expression as a sum or difference of logarithms or multiples of logarithms. log2 (x^9 y^5 / 8)

options:
1) 9log2 x -5log2 y -log2 8
2) 9log2 x +5log2 y -log2 8
3) (9log2 x)(5log2 y) -log2 8
4) 9log2 x +5log2 y +log2 8

12. decide whether each statement is always true, sometimes true, or never true. a. when corresponding points of an original figure and its reflection are connected, the resulting segments are all perpendicular to the line of reflection. b. when a point is reflected over a horizontal line, the y-coordinate of the point stays the same. answer both questions and explain
