Find the value of A that makes the following equation true for all values of x. 2x=A(12x)Choose 1 answer: (A) A=2×12(B) A=2(121)(C) A=212(D) A=(121)2
Q. Find the value of A that makes the following equation true for all values of x. 2x=A(12x)Choose 1 answer: (A) A=2×12(B) A=2(121)(C) A=212(D) A=(121)2
Simplify Equation: Simplify the equation to find A:2x=A(12x)To make the equation true for all x, the bases and exponents on both sides must be equal.
Set Exponents Equal: Set the exponents equal to each other:Since the bases are different, equate the exponents:x=12xThis step is incorrect because it does not help in solving for A. We need to equate the bases instead.
