[tex]( \frac{2}{7}) {}^{ - 24} = ( \frac{7}{2} ) {}^{24} = \frac{7 {}^{24} }{2 {}^{24} } [/tex]
b)
[tex]( \frac{1}{3} ) {}^{14} \div ( \frac{1}{3} ) {}^{12} = ( \frac{1}{3} ) {}^{2} = \frac{1}{9} [/tex]
c)
[tex] \frac{3 {}^{30} }{5 {}^{30} } [/tex]
d)
[tex]( \frac{5}{11} ) {}^{45} \times ( \frac{5}{11} ) {}^{20} \div ( \frac{5}{11} ) {}^{65} = 1[/tex]
Sper că te-am ajutat!
