Answer 1

a)

$\frac{ \frac{31 {}^{4} }{100 {}^{4} } \frac{25 {}^{2} }{10 {}^{2} } }{ \frac{25}{10} \frac{31 {}^{3} }{100 {}^{3} } } = \frac{31 {}^{4} \times 25 {}^{2} \times 10 \times 10 {}^{6} }{10 {}^{8} \times 10 {}^{2} \times 25 \times 31 {}^{3} }$

Simplificando

$\frac{31 \times 25}{10 {}^{3} } = \frac{31}{40}$

b)

$\frac{ - \frac{2 {}^{3} }{100 {}^{3} } \frac{12 {}^{4} }{10 {}^{4} } }{ \frac{12 {}^{2} }{10 {}^{2} } ( - \frac{2 {}^{2} }{100 {}^{2} } )} = - \frac{2 {}^{3} \times 12 {}^{4} \times 10 {}^{2} \times 10 {}^{4} }{12 {}^{2} \times 2 {}^{2} \times 10 {}^{6} \times 10 {}^{4} }$

$- \frac{18}{625}$

c)

$\frac{14 {}^{2} \times 19 {}^{2} }{19 {}^{4} }$

Simplificando

$\frac{196}{361}$

d)
