Question

5,3² b) 4,5³ c) 1,21³ d) 2,25² e) 1,73³ f) 5,12²

Answer 1

Resposta:

A)

$5.3 {}^{2} \\ ( \frac{53}{10}) {}^{2} \\ \frac{53 {}^{2} }{10 {}^{2} } = \frac{2809}{10 {}^{2} } = \frac{2809}{100}$

B)

$4.5 {}^{3} \\ ( \frac{9}{2}) {}^{3} = \frac{9 {}^{3} }{2 {}^{3} } \\ \frac{729}{ {2}^{3} } = \frac{729}{8}$

C)

$1.21 {}^{3} \\ ( \frac{121}{100}) {}^{3} = \frac{121 {}^{3} }{100 {}^{3} }$

D)

$2.25 {}^{2} \\ ( \frac{9}{4}) {}^{2} = \frac{9 {}^{2} }{4 {}^{2} } \\ \frac{81}{4 {}^{2} } = \frac{81}{16}$

E)

$1.73 {}^{3} \\ ( \frac{173}{100}) {}^{3} = \frac{173 {}^{3} }{100 {}^{3} }$

F)

$5.12 {}^{2} \\ ( \frac{128}{25}) {}^{2} \\ \frac{128 {}^{2} }{25 {}^{2} } = \frac{16384}{25 {}^{2} } = \frac{16384}{625}$
