Answer 1

Respuesta:

$a) {( \frac{3}{2} )}^{3} + {( \frac{3}{4} )}^{2} = \frac{27}{8} + \frac{9}{16} = \frac{54}{16} + \frac{9}{16} = \frac{63}{16}$

$b) {( \frac{7}{8} )}^{ - 2} = {( \frac{8}{7} )}^{2} = \frac{64}{49}$

$c) {( \frac{5}{3} )}^{3} = \frac{125}{27}$

$d) {( \frac{6}{5} )}^{ - 2} - {( \frac{1}{4} )}^{2} = {( \frac{5}{6} )}^{2} - {( \frac{1}{4} )}^{2} = \frac{25}{36} - \frac{1}{16} = \frac{100}{144} - \frac{9}{144} = \frac{91}{144}$
