Answer 2

Answer:

$\frac{75076}{83521}$

Step-by-step explanation:

548 x 518 x 548 x 432 x 432 x 432 ÷  578 x 578 -  578 x 432 x 432 x 432

= $\frac{548 * 518 * 548 * 432 * 432 * 432}{ 578 * 578 * 578 * 432 * 432 * 432}$

= $\frac{548^{2} * 432^{3} * 578}{ 578^{3} * 432^{3}}$  ​

= $\frac{548^{2}}{ 578^{2} }$

= $(\frac{548}{578}) ^{2}$

= $(\frac{2 * 2 * 137}{2 * 17 * 17}) ^{2}$

= $(\frac{2 * 137}{17 * 17}) ^{2}$

= $(\frac{274}{289}) ^{2}$

= $\frac{75076}{83521}$
