Question

помогите пожалуйста

1)
$\frac{p}{ {q}^{2} } + \frac{3p}{q {}^{2} }$
2)
$\frac{a}{a + b} + \frac{c}{a + b}$
3)

$\frac{1}{ab} + \frac{1}{bc}$
4)
$\frac{3c}{ {4a}^{3} b} + \frac{5d}{6ab {}^{3} }$
5)
$\frac{2}{3y {}^{3} } - \frac{1}{6x {}^{2}y } + \frac{5}{12xy {}^{2} }$
6)
$\frac{a}{b {}^{2} } + \frac{b}{c {}^{2} } + \frac{c}{a {}^{2} }$

Answer 1

1.(p+3p)/q²=4p/q²
2.(a+с)/(a+b)
3.(a+с)/abс
4.(9b²с+10a²д)12a³b³
5.(8x²-2y+5[)/12x²y²
6.(a³с²+b³a²+b²с²)/a²b²с²=a²b²с²(a+b+с)/a²b²с²=a+b+с
