\(\frac{\left(0.6\right)^5}{\left(0.2\right)^6}=1215\)

còn lại làm đc mà

\(\frac{\left(0,6\right)^5}{\left(0,2\right)^6}=\frac{\left(0,2\right)^5\cdot3^5}{\left(0,2\right)^6}=\frac{3^5}{0.2}=243:\frac{1}{5}=1215\)

\(\frac{2^7\cdot9^3}{6^5\cdot8^2}=\frac{2^7\cdot\left(3^2\right)^3}{2^5\cdot3^5\cdot\left(2^3\right)^2}=\frac{2^7\cdot3^6}{2^{11}\cdot3^5}=\frac{3}{2^4}=\frac{3}{16}\)

câu cuối ko bt

Xin lỗi vì đã ns dối, ko phải tớ ko bt giải mà là tại mama kêu ghê quá nên ko kịp viết lời giải câu cuối !

\(\frac{6^3+3\cdot6^2+3^3}{-13}=\frac{2^3\cdot3^3+3\cdot2^2\cdot3^2+3^3}{-13}=\frac{2^3\cdot3^3+3^3\cdot2^2+3^3}{-13}=\frac{3^3\left(2^3+2^2+1\right)}{-13}=\frac{27\cdot13}{-13}=-27\)

Ko sao nhưng học mà cũng bị kêu mama bn chắc dữ lắm

hôm qua làm rồi giờ đăng gì nữa @-@

trời ạ         

a.\(=\frac{2^4.2^6}{2^{10}}\)

\(=\frac{2^{10}}{2^{10}}=1\)

b, \(=\frac{\left[3^5.0,2^5\right]}{0.2^6}\)

\(=\frac{243}{0.2}\)

\(=1215\)

c,\(=\frac{2^7.3^9}{2^5.3^5.2^6}\)

\(=\frac{3^4}{2^4}\)

\(=1\frac{1}{2}\)

d,\(=\frac{2^3.3^3+3.2^2.3^2+3^3}{-13}\)

\(=\frac{3^3.\left(2^3+2^2+1\right)}{-13}\)

\(=\frac{3^3.13}{-13}\)

=-27
