Q. Find the value of x x that solves the equation ln(x1)+12ln16=ln2 \ln (x-1)+\frac{1}{2} \ln 16=\ln 2 .\newlineAnswer: x= x=
  1. Simplify equation: First, we need to simplify the equation using properties of logarithms. The equation is ln(x1)+12ln16=ln2\ln(x-1) + \frac{1}{2}\ln 16 = \ln 2. We know that 12ln16\frac{1}{2}\ln 16 can be simplified because ln16\ln 16 is the natural log of 22 to the power of 44, so 12ln16\frac{1}{2}\ln 16 is the same as ln1612\ln 16^{\frac{1}{2}} or ln4\ln 4.
  2. Rewrite with simplification: Now we rewrite the equation using the simplification from the previous step: ln(x1)+ln4=ln2\ln(x-1) + \ln 4 = \ln 2.
  3. Combine left side: Using the property of logarithms that lna+lnb=ln(ab)\ln a + \ln b = \ln(ab), we can combine the left side of the equation: ln((x1)4)=ln2\ln((x-1)\cdot 4) = \ln 2.
  4. Simplify left side: Simplify the left side of the equation to get ln(4x4)=ln2\ln(4x-4) = \ln 2.
  5. Set up equation: Since the natural log function is one-to-one, if ln(4x4)=ln2\ln(4x-4) = \ln 2, then 4x44x-4 must be equal to 22. We can now solve for xx by setting 4x44x-4 equal to 22.
  6. Isolate x term: Add 44 to both sides of the equation to isolate the term with xx: 4x4+4=2+44x-4+4 = 2+4, which simplifies to 4x=64x = 6.
  7. Solve for x: Divide both sides of the equation by 44 to solve for x: 4x4=64\frac{4x}{4} = \frac{6}{4}, which simplifies to x=64x = \frac{6}{4} or x=1.5x = 1.5.
