Answer 1

${(0.3)}^{ frac{ {x}^{2} - x - 12 }{x} } = 1 \ {(0.3)}^{ frac{ {x}^{2} - x - 12 }{x} } = {(0.3)}^{0} \ frac{ {x}^{2} - x - 12 }{x} = 0 \ {x}^{2} - x - 12 = 0 \ d = {b}^{2} - 4ac = 1 - 4 times 1 times ( - 12) = 1 + 48 = 49 \ x1 = frac{1 + 7}{2} = 4 \ x2 = frac{1 - 7}{2} = - 3$
4*(-3) = -12

Answer 2
