Full solution

Q. Find the positive solution of the equation.\newline4x79+28=65564 4 x^{\frac{7}{9}}+28=65564 \newlineAnswer:
  1. Isolate variable x: Subtract 2828 from both sides of the equation to isolate the term with the variable xx.\newline4x(7/9)+2828=65564284x^{(7/9)} + 28 - 28 = 65564 - 28\newline4x(7/9)=655364x^{(7/9)} = 65536
  2. Solve for x79x^{\frac{7}{9}}: Divide both sides of the equation by 44 to solve for x79x^{\frac{7}{9}}.4x794=655364\frac{4x^{\frac{7}{9}}}{4} = \frac{65536}{4}x79=16384x^{\frac{7}{9}} = 16384
  3. Recognize power of 22: Recognize that 1638416384 is a power of 22. Specifically, 16384=21416384 = 2^{14}. x79=214x^{\frac{7}{9}} = 2^{14}
  4. Raise to reciprocal exponent: Raise both sides of the equation to the reciprocal of 79\frac{7}{9} to solve for xx.(x79)97=(214)97\left(x^{\frac{7}{9}}\right)^{\frac{9}{7}} = \left(2^{14}\right)^{\frac{9}{7}}x=21497x = 2^{14 \cdot \frac{9}{7}}
  5. Simplify exponent: Simplify the exponent on the right side of the equation. x=218x = 2^{18}
  6. Calculate final value: Calculate 2182^{18} to find the value of xx.\newlinex=262144x = 262144
