Question

If 27^x=9/3^x find x​

Answer 1

Answer:

27^x=9/3^x

27^x × 3^x= 9

81^x=9

x=81/9

x=9

Answer 2

Answer:

x=1/2

Step-by-step explanation:

${27}^{x} = \frac{9}{ {3}^{x} } . \\ {(3)}^{3x} \times {(3)}^{x} = 9. \\ {(3)}^{3x + x} = {(3)}^{2} . \\ {(3)}^{4x} = {(3)}^{2} . \\ from \: law \: of \: indices. \\ 4x = 2. \\ x = \frac{2}{4} = \frac{1}{2} .$
