Answer 1

Răspuns:

g)

$\frac{125}{8} \div ( \frac{5}{2} ) {}^{2} = \frac{125}{8} \div \frac{25}{4} = \frac{125}{8} \times \frac{4}{25} = \frac{5}{2}$

h)

$( \frac{11}{13} ) {}^{49} \div ( \frac{11}{1 3} ) {}^{49} = 1$

i)

$(2 \times \frac{1}{3} ) {}^{36} \div ( \frac{49}{9} ) {}^{17} = ( \frac{7}{3} ) {}^{36} \div ( \frac{49}{9} ) {}^{17} = ( \frac{7}{3} ) {}^{36} \div ( \frac{7 {}^{2} }{3 {}^{2} } ) {}^{17} = ( \frac{7}{3} ) {}^{36} \div( ( \frac{7}{3} ) {}^{2} ) {}^{17} = ( \frac{7}{3} ) {}^{36} \div ( \frac{7}{3} ) {}^{34} = ( \frac{7}{3} ) {}^{2} = \frac{49}{9}$
