\(\frac{\left(0,6\right)^5.\left(0,3\right)^3}{\left(0,2\right)^6.\left(0,3\right)^7}\)

\(=\frac{\left(\frac{6}{10}\right)^5.\left(\frac{3}{10}\right)^3}{\left(\frac{2}{10}\right)^6.\left(\frac{3}{10}\right)^7}\)

\(=\frac{6^5.3^3.\frac{1}{10^8}}{2^6.3^7.\frac{1}{10^{13}}}\)

\(=\frac{2^5.3^5.3^3}{2^6.3^7.\frac{1}{10^5}}\)

\(=\frac{10^5.3}{2}\)

\(=150000\)

\(\frac{\left(0,2.3\right)^5}{0,2^6}\)=\(\frac{0,2^5.3^5}{0,2^6}\)=\(\frac{3^5}{0,2}\)=\(\frac{243}{0,2}\)=1215

\(\frac{\left(0,6\right)^5}{\left(0,2\right)^6}=\frac{\left(0,2.3\right)^5}{\left(0,2\right)^6}=\frac{\left(0,2\right)^5.3^5}{\left(0,2\right)^6}=\frac{3^5}{0,2}=\frac{243}{0,2}=1215\)

em khong biet lam em hoc lop 4 ma

\(\frac{\left(0,6\right)^5}{\left(0,2\right)^6}=\frac{\left(0,2\right)^5\cdot3^5}{\left(0,2\right)^6}=\frac{243}{0,2}=1215\)

1215 bạn nhé

c) \(\frac{0,375-0,3+\frac{3}{11}+\frac{3}{12}}{0,625-0,5+\frac{5}{11}+\frac{5}{12}}=\frac{3\left(0,125-0,1+\frac{1}{11}+\frac{1}{12}\right)}{5\left(0,123-0,1+\frac{1}{11}+\frac{1}{12}\right)}=\frac{3}{5}\)

Sai thôi nha

( 1 / 6 )²  . 6² + ( 0,6 ) ⁵ / ( 0 , 2 ) ⁶

= 1 + 3⁵ . (0 , 2)⁵ / 0,2 . ( 0, 2 )⁵

=1 + 3⁵ / 0, 2

= 1 +  243 : 2 / 10

= 1 + 1215

= 1216

\(\frac{\left(0,6\right)^5}{\left(0,2\right)^6}=\frac{\left(0,2.3\right)^5}{\left(0,2\right)^6}=\frac{\left(0,2\right)^5.3^5}{\left(0,2\right)^6}=\frac{3^5}{0,2}=\frac{243}{0,2}=1215\)
