Q. Find the value of x x that solves the equation ln(x+2)13ln8=ln2 \ln (x+2)-\frac{1}{3} \ln 8=\ln 2 .\newlineAnswer: x= x=
  1. Simplify using properties: To solve the equation ln(x+2)(13)ln8=ln2\ln(x+2)-(\frac{1}{3})\ln 8=\ln 2, we first need to simplify the equation by using the properties of logarithms.
  2. Rewrite using power rule: Using the power rule of logarithms, which states that ln(ab)=bln(a)\ln(a^b) = b\cdot\ln(a), we can rewrite (1/3)ln8(1/3)\ln 8 as ln(81/3)\ln(8^{1/3}).
  3. Combine logarithms: Since 81/38^{1/3} is the cube root of 88, which is 22, we can further simplify the equation to extln(x+2)extln(2)=extln(2) ext{ln}(x+2) - ext{ln}(2) = ext{ln}(2).
  4. Equation simplification: Now, we can use the property of logarithms that ln(a)ln(b)=ln(ab)\ln(a) - \ln(b) = \ln\left(\frac{a}{b}\right) to combine the left side of the equation into a single logarithm: ln(x+22)=ln(2)\ln\left(\frac{x+2}{2}\right) = \ln(2).
  5. Equating arguments: Since the logarithmic function is one-to-one, if ln(a)=ln(b)\ln(a) = \ln(b), then a=ba = b. Therefore, we can equate the arguments of the logarithms: x+22=2\frac{x+2}{2} = 2.
  6. Multiply to solve: To solve for xx, we multiply both sides of the equation by 22 to get x+2=4x+2 = 4.
  7. Subtract to find: Finally, we subtract 22 from both sides to find the value of xx: x=42x = 4 - 2.
  8. Final solution: So, the value of xx that solves the equation is x=2x = 2.
