Question

[Phan Mai Hoa]

Bài 1:

a)  \(\frac{\left(0,6\right)^5}{\left(0,2\right)^6}\)

b)  \(\frac{2^7.9^3}{6^5.8^2}\)

c) \(\frac{3^3+3.6^2+3^3}{-13}\)

Answer 1

[Ridofu Sarah John]

\(\frac{\left(0,6\right)^5}{\left(0,2\right)^6}=\frac{\left(0,6\right)^5}{\left(0,2\right)^5.0,2}=\left(\frac{0,6}{0,2}\right)^5.\frac{1}{\frac{1}{5}}=3^5.5=243.5=1215\)

Answer 2

[Ridofu Sarah John]

\(\frac{2^7.9^3}{6^5.8^2}=\frac{2^7.\left(3^2\right)^3}{\left(2.3\right)^5.\left(2^3\right)^2}=\frac{2^7.3^6}{2^5.3^5.2^6}=\frac{2^7.3.3^5}{2^7.2^4.3^5}=\frac{3}{16}\)
