1.If (a+bx)−3=127+13x+…(a + bx)^{-3} = \frac{1}{27} + \frac{1}{3}x + \ldots(a+bx)−3=271+31x+…, then the ordered pair (a,b)(a, b)(a,b) equalsa.(3,−27)(3, -27)(3,−27)b.(1,13)(1, \frac{1}{3})(1,31)c.(3,9)(3, 9)(3,9)d.(3,−9)(3, -9)(3,−9)Login to continueOnly logged in users canattempt or see the solution.
