\(A=\frac{\left(5^2\right)^3\cdot5^5}{6\cdot5^{10}}\)
\(A=\frac{5^{2+3}\cdot5^5}{6\cdot5^{10}}\)
\(A=\frac{5^5\cdot5^5}{6\cdot5^{10}}\)
\(A=\frac{5^{5+5}}{6\cdot5^{10}}\)
\(A=\frac{5^{10}}{6\cdot5^{10}}\)
\(\Rightarrow A=\frac{1}{6}\)
\(A=\frac{25^3.5^5}{6.5^{10}}=\frac{\left(5^2\right)^3.5^5}{6.5^{10}}=\frac{5^5.5^5}{6.5^{10}}=\frac{1}{6}.\)
Bài này là bài đại trà của lp 6 bn ạ, ko phải lp 7
A = 253.55/6.510
A = (52)3.55/6.510
A = 56.55/6.510
A = 511/6.510
A = 5/6
\(\frac{25^3.5^5}{6.5^{10}}=\frac{5^6.5^5}{6.5^{10}}=\frac{5^{11}}{6.5^{10}}=\frac{5.5^{10}}{6.5^{10}}=\frac{5}{6}\)
A = 253.55/6.510
A = (52)3.55/6.510
A = 56.55/6.510
A = 511/6.510
A = 5/6
