Trả lời
(22.23/42.16)15:(26/162)10
=[25/(22)2.24 ]15:[26/(24)2 ]10
=(25/28)15:(26/28)10
=1/815:1/410
=1/815:1/85
=1/810
Ko chắc !
\(\left(\frac{2^2.2^3}{4^2.16}\right)^{15}:\left(\frac{2^6}{16^2}\right)^{10}\)
\(=\left(\frac{2^5}{2^4.16}\right)^{15}:\left(\frac{2^6}{2^8}\right)^{10}\)
\(=\left(\frac{2}{16}\right)^{15}:\left(2^{-2}\right)^{10}\)
\(=\left(\frac{1}{8}\right)^{15}:2^{-20}\) -> đổi (1/8)15 = (1/23)15 = 1/245 = 2-45
\(=2^{-45}:2^{-20}\)
\(=2^{-25}=\frac{1}{2^{25}}\)
Hơi tắt chút
