The value of x such that (3 / 7)³ x (3 / 7)⁻⁸ = (3 / 7)²ˣ⁺³ is (a) -4 (b) -2 (c) 0 (d) 1

Question

KnowledgeBoat · Accepted Answer

Given: LHS = Now, LHS = As the base of both LHS and RHS is same, let us compare the exponents: -5 = 2x + 3 2x = -5 - 3 2x = -(5 + 3) 2x = -8 x = x = -4 Hence, option 1 is the correct option.
