Full solution

Q. Find the positive solution of the equation.\newline4x6726=230 4 x^{\frac{6}{7}}-26=230 \newlineAnswer:
  1. Add 2626 to isolate: Add 2626 to both sides of the equation to isolate the term with the variable.\newline4x(6/7)26+26=230+264x^{(6/7)} - 26 + 26 = 230 + 26\newlineSimplify the equation.\newline4x(6/7)=2564x^{(6/7)} = 256
  2. Simplify the equation: Divide both sides of the equation by 44 to solve for x67x^{\frac{6}{7}}.4x674=2564\frac{4x^{\frac{6}{7}}}{4} = \frac{256}{4}Simplify the equation.\text{Simplify the equation.}x67=64x^{\frac{6}{7}} = 64
  3. Divide by 44: Raise both sides of the equation to the reciprocal of 67\frac{6}{7} to solve for xx.\newline(x67)76=6476(x^{\frac{6}{7}})^{\frac{7}{6}} = 64^{\frac{7}{6}}\newlineSimplify the exponents on the left side.\newlinex=6476x = 64^{\frac{7}{6}}
  4. Raise to reciprocal: Calculate 647664^{\frac{7}{6}}.\newlineSince 6464 is 22 raised to the 66th power (262^6), we can rewrite 647664^{\frac{7}{6}} as (26)76(2^6)^{\frac{7}{6}}.\newline(26)76=2676(2^6)^{\frac{7}{6}} = 2^{6 \cdot \frac{7}{6}}\newlineSimplify the exponents.\newline2676=272^{6 \cdot \frac{7}{6}} = 2^7\newlineCalculate 272^7.\newline646400
