\(\frac{3^6\cdot45^5-15^3\cdot5^9}{27\cdot25^3+45^6}\)
\(=\frac{3^6\cdot3^{10}\cdot5^5-3^3\cdot5^3\cdot5^9}{3^{12}\cdot5^6+5^6\cdot3^{12}}\)
\(=\frac{3^{16}\cdot5^5-3^3\cdot5^{12}}{2\cdot3^{12}\cdot5^6}=\frac{3^3\cdot5^5\left(3^{13}-5^7\right)}{2\cdot3^{12}\cdot5^6}=\frac{3^{13}-5^7}{2\cdot3^9\cdot5}\)
\(=\frac{3^{13}}{2\cdot3^9\cdot5}-\frac{5^7}{2\cdot3^9\cdot5}=\frac{81}{10}-\frac{5^6}{2\cdot3^9}\)
haiz!đến đây tịt!có sai đề ko bạn?
\(A=\frac{3^6.45^5-15^3.5^9}{27^4.25^3+45^6}\)
\(A=\frac{3^6.\left(3^2.5\right)^5-\left(3.5\right)^3.5^9}{\left(3^3\right)^4.\left(5^2\right)^3+\left(3^2.5\right)^6}\)
\(A=\frac{3^6.3^{10}.5^5-3^3.5^3.5^9}{3^{12}.5^6+3^{12}.5^6}\)
\(A=\frac{3^{16}.5^5-3^3.5^{12}}{3^{12}.5^6+3^{12}.5^6}\)
\(A=\frac{3^3.5^5.\left(3^{13}-5^7\right)}{2.3^{12}.5^6}\)
\(A=\frac{3^{13}-5^7}{2.3^9.5}\)
Có gì đó sai sai
Sr sr :v Lộn nha :v \(A=\frac{3^6.45^4-15^3.5^9}{27^4.25^3+45^6}\) . Sao lần nào đăng cũng sai đề vậy nhỉ :>
\(\frac{3^6\cdot45^4-15^3\cdot5^9}{27^4\cdot25^3+45^6}\)
\(=\frac{3^6\cdot5^4\cdot3^8-3^3\cdot5^3\cdot5^9}{2\cdot3^{12}\cdot5^6}\)
\(=\frac{3^{14}\cdot5^4-3^3\cdot5^{12}}{2\cdot3^{12}\cdot5^6}\)
\(\frac{3^3\cdot5^4\left(3^{11}-5^8\right)}{2\cdot3^{12}\cdot5^6}\)
\(=\frac{3^{11}-5^8}{2\cdot3^9\cdot5^2}=\frac{3^{11}}{2\cdot3^9\cdot5^2}-\frac{5^8}{2\cdot3^9\cdot5^2}=\frac{9}{50}-\frac{5^6}{2\cdot3^9}\)
mik sai đừng ném đá(hình như sai đề phải)
\(A=\frac{3^6.45^4-15^3.5^9}{27^4.25^3+45^6}\)
\(A=\frac{3^6.\left(3^2.5\right)^4-\left(3.5\right)^3.5^9}{\left(3^3\right)^4.\left(5^2\right)^3+\left(3^2.5\right)^6}\)
\(A=\frac{3^6.3^8.5^4-3^3.5^3.5^9}{2.3^{12}.5^6}\)
\(A=\frac{3^3.5^4.\left(3^{11}-5^8\right)}{2.3^{12}.5^6}\)
\(A=\frac{3^{11}-5^8}{2.3^9}\)
\(A=\frac{9}{2}-\frac{5^8}{2.3^9}\)
Lạ
kudo shinichi:hình như anh sai phải ah.\(\frac{5^4}{5^6}=\frac{1}{5^2}\)
Mí bn giải thế nào thì ko bt
Nhưng góp í chỗ mẫu
chỗ \(2.3^{12}.5^6\) thêm dấu ngoặc nhìn đúng hơn \(2\left(3^{12}.5^6\right)\)
P/s : ý kiến riêng thoi :v
\(A=\frac{3^6.45^4-15^3.5^9}{27^4.25^3+45^6}\)
\(\Rightarrow A=\frac{3^6.\left(5.9\right)^4-\left(5.3\right)^3.5^9}{\left(3^3\right)^4.\left(5^2\right)^3+\left(5.9\right)^6}\)
\(\Rightarrow A=\frac{3^6.5^4.9^4-5^3.3^3.5^9}{3^{12}.5^6+5^6.9^6}\)
\(\Rightarrow A=\frac{3^6.5^4.\left(3^2\right)^4-5^{12}.3^3}{3^{12}.5^6+5^6.9^6}\)
\(\Rightarrow A=\frac{3^6.5^4.3^8-5^{12}.3^3}{3^{12}.5^6+5^6.9^6}\)
\(\Rightarrow A=\frac{3^{14}.5^4-5^{12}.3^3}{3^{12}.5^6+5^6.9^6}\)
