Answer:

{ \bf{ =  \sin(4x)  + 2 \sin(2x) }} \\  = { \bf{2 \sin(2x) \cos(2x)   + 4 \sin(x)  \cos(x) }} \\  { \bf{ = 4 \sin(x) \cos(x) . ({ \cos }^{2}  x -  { \sin}^{2} }x) + 4 \sin(x) \cos(x)  }  \\  = { \bf{4 \sin(x) \cos(x)  ( { \cos }^{2}x -  { \sin }^{2}x + 1)  }} \\  = { \bf{4 \sin(x) \cos(x)  }(2 { \cos }^{2} x)} \\  = { \bf{8 \sin(x)  { \cos}^{3}x }}

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute -12:                              -12x - 48 + 14x = 60
  2. Combine like terms:                   2x - 48 = 60
  3. Add 48 to both sides:                 2x = 108
  4. Divide 2 on both sides:              x = 54

Use the definition of the logarithmic function to find x. log4 0.25=x x=?
GREYUIT [131]
The answer is -1.

log_4(0.25)  =log_4( \frac{1}{4})= log_4(4^{-1} ) \\  \\ &#10;log(x^{a} ) = a*log(x) \\  \\ &#10;log_4(4^{-1} )= -1 *log_4(4) \\  \\ &#10;log_y(x) =  \frac{log(x)}{log(y)}  \\  \\ &#10;-1 *log_4(4) = -1* \frac{log(4)}{log(4)} = -1
