Respuesta:
a) 0
b) 4
Explicación paso a paso:
[tex] \frac{ {20}^{2} \times {3}^{2} }{ {5}^{2} } = \frac{ {5}^{2} \times {4}^{2} \times {3}^{2} }{ {5}^{2} } [/tex]
[tex] = {4}^{2} \times {3}^{2} = 16 \times 9 = 144[/tex]
[tex] {12}^{2} = 144[/tex]
144-144=0 a)
[tex] ((({2}^{ \frac{4}{5} } )^{ \frac{5}{2} } ) ^{ \frac{7}{3} } ) ^{ \frac{3}{7} } [/tex]
[tex] = {2}^{ \frac{4}{5} \times \frac{5}{2} \times \frac{7}{3} \times \frac{3}{7} } = {2}^{2} = 4[/tex]
