Answer:

\frac{ {7}^{4} ( - 2) {}^{4} {11}^{3}  6}{7 {}^{3}    {2}^{2} {6}^{2} 11 {}^{2}   }  =  \frac{7 \times  {2}^{2}  \times 11}{6}  =  \frac{308}{6}  =  \frac{154}{3}   \\  \\  \frac{ {7}^{0} {12}^{0}  {17}^{0}  }{ {57}^{0}  + ( {42}^{0}  \times ( {13}^{0} ))}  =  \frac{1}{1 + 1}  =  \frac{ 1}{2}

What is the sum? 3 y / Y 2 + 7 y + 10 + 2 / y + 2​
kap26 [50]

Answer:

  5/(y+5)

Step-by-step explanation:

Perhaps you want the sum ...

  \dfrac{3y}{y^2+7y+10}+\dfrac{2}{y+2}\\\\=\dfrac{3y}{(y+2)(y+5)}+\dfrac{2(y+5)}{(y+2)(y+5)}=\dfrac{3y+2(y+5)}{(y+2)(y+5)}\\\\=\dfrac{5y+10}{(y+2)(y+5)}=\dfrac{5(y+2)}{(y+2)(y+5)}=\boxed{\dfrac{5}{y+5}}

<em>Comment on rational expressions</em>

When writing ratios in plain text, it is imperative to put parentheses around numerators and denominators. (If the numerator is a product only, then parentheses are optional.)

Your expression might be properly written as ...

  3y/(y^2 +7y +10) +2/(y+2)

As you have written it, it simplifies to ...

  3(y/y)2 +7y +10 +2/y +2 = 3·2 +7y +2/y +12

  = 7y +2/y +18

Please note, too, the exponentiation symbol (^).
