\(\frac{9^6.16^4}{27^4.8^3}\)
CMR 12^18 = 27^6.16^9
\(12^{18}=\left(2^2.3\right)^{18}=2^{36}.3^{18}\)
\(27^6.16^9=\left(3^3\right)^6.\left(2^4\right)^9=3^{18}.2^{36}\)
=> 1218=276.169
(4/15-1/6).x=-3/4.8/27
(4/15-1/6)x = -3/4.8/27
=> 1/10x = -2/9
=> x = -20/9
Trả lời
(4/15-1/6)x=-3/4.8/27
1/10x=-2/9
x=-2/9:1/10
x=-20/9
Trong bài có sai sót mong bạn bỏ qua !
\(\left(\frac{4}{15}-\frac{1}{6}\right).x=-\frac{3}{4}.\frac{8}{27}\)
\(\Leftrightarrow\frac{1}{10}x=-\frac{2}{9}\)
\(\Leftrightarrow x=-\frac{20}{9}\)

\(A=\frac{\frac{15}{6.16}+\frac{15}{16.26}+\frac{15}{26.36}}{\frac{33}{6.16}-\frac{63}{16.26}+\frac{93}{26.36}}\)

Thực hiện phép tính: \(B=\frac{2^6.3^5-9^2.4^3}{4^3.9^2-3^4.8^2}\)
\(=\frac{\left(2^2\right)^3.3^5-\left(3^2\right)^2.4^3}{\left(2^2\right)^3.9^2-\left(3^2\right)^2.\left(2^3\right)^2}=\frac{4^3.3^5-3^4.4^3}{2^6.9^2-9^2.2^6}=\frac{4^3.\left(3^5-3^4\right)}{9^2.\left(2^6-2^6\right)}=\frac{162}{0}\)
