A and B solve the equations ax + 5Y = 15 ①, 4x + by = - 2 ② together. Because a misread the letter A, we get the equations ① x = - 3, y = - 1. B misread the letter B, The solution to the equations is x = 5, y = 4. Try to calculate the value of a to the power of 2010 + (- 0.1b) to the power of 2009

∵ a misread a in equation ① to get the solution x = - 3, y = 1 ∵ substituting x = - 3, y = 1 into ② to get: - 12-B = - 2 to get the solution B = - 10 ∵ B misread B in equation ② to get the solution x = 5, y = 4 ∵ substituting x = 5, y = 4 into ① to get: 5A + 20 = 15 to get the solution a = - 1; ∵ (- 1) ^ 2010 + [(- 0.1) * (- 10)
