Помогите пожалуйста(24,25)

24.
$1\frac{24}{25} = \frac{49}{25} = (\frac{7}{5})^2$

25.
$M = \frac{27*2^3-2^4}{6^2+8^2} = \frac{27*2^3-2*2^3}{6^2+8^2} = \frac{25*2^3}{6^2+8^2} = \frac{25*2^3}{4(3^2+4^2)} = \frac{25*2}{3^2+4^2} = \frac{25*2}{25} = 2\\$
$N =\frac{15*3^2 + 5^2}{(-4)^4+4*17^0} = \frac{15*3^2 + 5^2}{4^4+4} = \frac{5*3^3 + 5*5}{4^4+4} = \frac{5(27 + 5)}{4(4^3+1)} = \frac{5*32}{4(64+1)} = \frac{5*16}{65} = \frac{16}{13}$
$\frac{2*13}{13} \ \textgreater \ \frac{16}{13}\\ \frac{26}{13} \ \textgreater \ \frac{16}{13}\\ M \ \textgreater \ N$
