If 8 ∙ 2x = 5(y+8), then when y = -8, x =
Choose the correct choice from the following
A) 8  B) 2  C) 6  D) 0  E) 7
8 ∙ 2x = 5(y+8).   or, 8 ∙ 2x = 5(-8+8).   or, 2x = 50.   or, 2x = 1 [anything to the power 0 is 1 then, 50 = 1].   Taking log on both sides,   log 2x = log 1.   or, x log 2 = 0 [since log 1 = 0].   or, x = 0/log 2 [dividing log 2 on both sides].   Therefore, x = 0.   Answer:0
