Question

Me ajude calcular por favor .Obrigado

Answer 1

$\frac{(13 {}^{3} ) {}^{2} \times (13 {}^{ - 1} ) {}^{3} }{13 {}^{7} \times (13 {}^{5}) {}^{ - 1} } = \frac{13 {}^{3 \times 2} \times 13 {}^{ - 1 \times 3} }{13 {}^{7} \times 13 {}^{5 \times ( - 1)} } \\ \\ \frac{13 {}^{6} \times 13 {}^{ - 3} }{13 {}^{7} \times 13 {}^{ - 5} } = \frac{13 {}^{6 + ( - 3)} }{13 {}^{7 + ( - 5)} } = \frac{13 {}^{6 - 3} }{13 {}^{7 - 5} } \\ \\ \frac{13 {}^{3} }{13 {}^{2} } = 13 {}^{3 - 2} = 13 {}^{1} = 13$

Answer 2

Explicação passo-a-passo:

$\frac{ {( {13}^{3}) }^{2} . { ({13}^{ - 1}) }^{3} }{ {13}^{7}. { ({13}^{5}) }^{ - 1} } = \frac{ {13}^{6} . {13}^{ - 3} }{ {13}^{7} . {13}^{ - 5} } = \\ \\ \frac{ {13}^{ 6 - 3} }{ {13}^{7 - 5} } = \frac{ {13}^{3} }{ {13}^{2} } = {13}^{3 - 2} = {13}^{1} = 13$
