College Algebra: Lesson 7

If you are given data, then do a “regression” to find the equation. Remember: Double something: a=1, y=2. Express 161/2 = 4 in logarithmic form. A. log416 = ½ B. log164 = ½ C. log1/216 = 4 D. log41/2 = 16. 2) Express log2x + 4log2y as a single logarithm. A. log2xy4 B. log2x + y4 C. log2x + 4y D. log24xy ................
