Question

Find the value of x if left parenthesis 16 right parenthesis to the power of left parenthesis x minus 3 right parenthesis end exponent equals left parenthesis 2 right parenthesis to the power of left parenthesis x minus 6 right parenthesis end exponent.

  1. 0
  2. 1
  3. 2
  4. 4

hintHint:

If bases are equal , equate the power

The correct answer is: 2


    left parenthesis 16 right parenthesis to the power of left parenthesis x minus 3 right parenthesis end exponent equals left parenthesis 2 right parenthesis to the power of left parenthesis x minus 6 right parenthesis end exponent
    left parenthesis 2 right parenthesis to the power of left parenthesis 4 x minus 12 right parenthesis end exponent equals left parenthesis 2 right parenthesis to the power of left parenthesis x minus 6 right parenthesis end exponent
    4 space x minus 12 equals x minus 6
    3 space x equals 6
    x equals 2
