11-26.

Write each of the following expressions as a single simplified fraction, without negative exponents.

1. $\frac { x + 1 } { x } - \frac { x } { x - 1 }$

$\frac{(x+1)(x-1)}{x(x-1)}-\frac{x\cdot x}{x(x-1)}$

1. $( 1 - \frac { x } { y } ) ( \frac { x ^ { 2 } y ^ { 2 } } { y ^ { 3 } x - x ^ { 3 } y } )$

$\left(\frac{y-x}{y}\right)\left(\frac{x^2y^2}{xy(y^2-x^2)}\right)$

1. $\frac { x ^ { - 1 / 3 } - x ^ { - 4 / 3 } } { x ^ { - 4 / 3 } - x ^ { 2 / 3 } }$

$\frac{x^{-4/3}(x-1)}{x^{-4/3}(1-x^2)}$
