\frac{2}{y - 7} + \frac{1}{y - 4}

Least Common Multiplier of

y - 7, y - 4 : (y - 7) (y - 4)

Adjust Fractions based on the LCM

= \frac{2 ( y - 4 )}{( y - 7 ) ( y - 4 )} + \frac{y - 7}{( y - 7 ) ( y - 4 )}

Apply the fraction rule:

\frac{a}{c} + \frac{b}{c} = \frac{a + b}{c}

= \frac{2 ( y - 4 ) + y - 7}{( y - 7 ) ( y - 4 )}

Simplify

2 (y - 4) + y - 7 : 3 y - 15

= \frac{3 y - 15}{( y - 7 ) ( y - 4 )}

(\frac{x ^{- 3} y ^{4}}{5})^{- 3}

x (2 x + 3 (x - (3 x + 1)))

2 a (3 a^{5} 2 b^{4})^{3}

2 - \frac{x + 1}{x - 3}

\frac{x ^{- 3} - x}{x ^{- 2} - 1}
