Q. Find the positive solution of the equation.\newline4x56+6=4102 4 x^{\frac{5}{6}}+6=4102 \newlineAnswer:
  1. Isolate variable term: Isolate the term with the variable.\newlineSubtract 66 from both sides of the equation to isolate the term with the variable xx.\newline4x(5/6)+66=410264x^{(5/6)} + 6 - 6 = 4102 - 6\newline4x(5/6)=40964x^{(5/6)} = 4096
  2. Subtract to isolate xx: Divide both sides by 44 to solve for x56x^{\frac{5}{6}}.4x564=40964\frac{4x^{\frac{5}{6}}}{4} = \frac{4096}{4}x56=1024x^{\frac{5}{6}} = 1024
  3. Divide to solve x56x^{\frac{5}{6}}: Recognize that 10241024 is a power of 22. 10241024 is 22 raised to the power of 1010 because 210=10242^{10} = 1024. x56=210x^{\frac{5}{6}} = 2^{10}
  4. Recognize power of 22: Write the equation in terms of a common base.\newlineSince we have x56=210x^{\frac{5}{6}} = 2^{10}, we can express xx as 22 raised to some power.\newlineLet's find the power that 22 must be raised to in order to get xx by equating the exponents.\newline(56)×(the power of 2 that gives x)=10(\frac{5}{6}) \times (\text{the power of } 2 \text{ that gives } x) = 10
  5. Write in common base: Solve for the power of 22 that gives xx.\newlineMultiply both sides of the equation by 65\frac{6}{5} to solve for the power of 22.\newline65×56×(the power of 2 that gives x)=65×10\frac{6}{5} \times \frac{5}{6} \times \text{(the power of 2 that gives x)} = \frac{6}{5} \times 10\newline(the power of 2 that gives x)=12\text{(the power of 2 that gives x)} = 12
  6. Solve for power of 22: Write xx as 22 raised to the power of 1212.\newlineSince the power of 22 that gives xx is 1212, we can write xx as 2122^{12}.\newlinex=212x = 2^{12}
  7. Write xx as 2122^{12}: Calculate the value of 2122^{12}.
    212=2×2×2×2×2×2×2×2×2×2×2×22^{12} = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2
    212=40962^{12} = 4096
