Question

( 2/5) elevado a 4 =? ( 7/5) elevado a 11 ÷ ( 7/5) elevado a 4 =?

Answer 1

Respuesta:

1- $(\frac{2}{5})^4 = \frac{2^4}{5^4} = \frac{16}{625}$

2- $\frac{(\frac{7}{5})^{11}}{(\frac{7}{5})^{4}} = \frac{\frac{7^{11}}{{5}^{11}}}{\frac{7^{4}}{{5}^{4}}} = \frac{7^{11}*5^4}{5^{11}*7^4} = 7^7\frac{5^4}{5^{11}}$
