To simplify the complex fraction, let's first find a common denominator.
x/x + 4 = (x/x)(x/x+4) = x^2/(x(x+4))
Now, the complex fraction becomes:
x^2/(x(x+4)) / (1/x + 1/x+4)
Now, let's simplify the expression inside the complex fraction:
1/x + 1/x+4 = (x+4+x)/(x(x+4)) = (2x + 4)/(x(x+4))
Therefore, the complex fraction simplifies to:
x^2/(x(x+4)) / (2x + 4)/(x(x+4))
Now, we can rewrite this as a multiplication:
x^2/(x(x+4)) * (x(x+4)/(2x + 4))
The (x(x+4))/(x(x+4)) terms cancel out:
x^2 / (2x + 4)
Therefore, the simplified form of the complex fraction is x^2 / (2x + 4).
simplify the complex fraction x/x+4/(1/x + 1/x+4)
