will be the value of \( x \) ? (b) \( 2 x+1,3 x-1,3 x+5,5 x-7,51,63 \) and 70 are in ascending order. If the first quartileis 20 , what will be the value of \( x \) ?

Aplica el método de fracciones parciales a la función: \( \frac{x^2 + 2}{(x-1)(x+3)} \)

d) \( \frac{3^{4}: 3}{3^{2}}= \)

a) \( \left(3^{6}\right)^{7} \cdot 3^{2}: 3^{41}-5^{2}= \) c) \( \left[\left(2^{2}\right)^{3}\right]^{3}:\left(2^{3}\right)^{5}= \) e) \( 4^{3} \cdot\left(4^{5}\right)^{4}:\left(4^{3}\right)^{7}-2^{4}= \) g) \( \left[\left(5^{3}\right)^{12}:\left(5^{2}\right)^{17}-25\right]: 5= \) i) \( \left.2^{6}+10 \cdot\left[3 \cdot 3^{3}-\left(3^{4}\right)^{3}: 3^{11}\right)\right]= \)

If \( 33-a=a+27-5 a \), what is the value of \( 33+3 a ? \)

\( \frac { 4 x y } { x ^ { 2 } + y ^ { 2 } } \)
