Full solution

Q. Find the positive solution of the equation.\newline8x58+27=283 8 x^{\frac{5}{8}}+27=283 \newlineAnswer:
  1. Isolate Variable Term: Isolate the term with the variable.\newlineSubtract 2727 from both sides of the equation to isolate the term with the variable xx.\newline8x(5/8)+2727=283278x^{(5/8)} + 27 - 27 = 283 - 27\newline8x(5/8)=2568x^{(5/8)} = 256
  2. Subtract 2727: Divide both sides by 88 to solve for x58x^{\frac{5}{8}}.\newline8x588=2568\frac{8x^{\frac{5}{8}}}{8} = \frac{256}{8}\newlinex58=32x^{\frac{5}{8}} = 32
  3. Divide by 88: Recognize that 3232 is a power of 22. 3232 can be written as 252^5 because 25=322^5 = 32. x58=25x^{\frac{5}{8}} = 2^5
  4. Recognize Power of 22: Raise both sides of the equation to the reciprocal of the exponent on xx to solve for xx.(x5/8)8/5=(25)8/5(x^{5/8})^{8/5} = (2^5)^{8/5}x=258/5x = 2^{5 \cdot 8/5}x=28x = 2^8
  5. Raise to Reciprocal Exponent: Calculate 282^8 to find the value of xx.\newline28=2562^8 = 256\newlinex=256x = 256
