Multiple choice general knowledge math & puzzles log10(1000) = 8 + v , v=? -3 -5 -7 -1 Reveal answer Fill a bubble to check yourself B Correct answer Explanation First evaluate log10(1000) = 3, because 10^3 = 1000. The equation becomes 3 = 8 + v. Solving for v: v = 3 - 8 = -5. This problem tests knowledge of logarithms (log base 10 of 1000) combined with basic linear equation solving.
