If (0.2)x = 2 and log 2 = 0.3010, then Find the value of x to the nearest tenth.  Choose one:
A) -0.4 B) -0.2 C) -0.6 D) 0.4 E) 0.6
(0.2)x = 2.   Taking log on both sides   log (0.2)x = log 2.   x log (0.2) = 0.3010, [since log 2 = 0.3010].   x log (2/10) = 0.3010.   x [log 2 - log 10] = 0.3010.   x [log 2 - 1] = 0.3010,[since log 10=1].   x [0.3010 -1] = 0.3010, [since log 2 = 0.3010].   x[-0.699] = 0.3010.   x = 0.3010/-0.699.   x = -0.4306….   x = -0.4 (nearest tenth)   -0.4nswer is -0.4.
