Full solution

Q. Find the positive solution of the equation.\newline4x43+22=1046 4 x^{\frac{4}{3}}+22=1046 \newlineAnswer:
  1. Subtract 2222: Subtract 2222 from both sides of the equation to isolate the term with the variable xx.\newline4x(4/3)+2222=1046224x^{(4/3)} + 22 - 22 = 1046 - 22\newline4x(4/3)=10244x^{(4/3)} = 1024
  2. Divide by 44: Divide both sides of the equation by 44 to solve for x43x^{\frac{4}{3}}.4x434=10244\frac{4x^{\frac{4}{3}}}{4} = \frac{1024}{4}x43=256x^{\frac{4}{3}} = 256
  3. Recognize power of 22: Recognize that 256256 is a power of 22. Specifically, 256=28256 = 2^8.\newlinex43=28x^{\frac{4}{3}} = 2^8
  4. Take cube root: To solve for xx, we need to take the cube root of both sides and then raise them to the power of 33 to get rid of the exponent (4/3)(4/3).
    (x(4/3))(3/4)=(28)(3/4)(x^{(4/3)})^{(3/4)} = (2^8)^{(3/4)}
    x=2(8(3/4))x = 2^{(8*(3/4))}
    x=26x = 2^6
  5. Calculate value: Calculate 262^6 to find the value of xx.\newline26=642^6 = 64\newlinex=64x = 64
