(100 + 42 ).42 + 58(200 - 58)
= 142.42 + 58.142
= 142.(42 + 58)
= 142.100
= 14200
Ta có: \(1-\frac{2011}{2012}=\frac{1}{2012}\)
\(1-\frac{2013}{2014}=\frac{1}{2014}\)
Có: \(\frac{1}{2012}>\frac{1}{2014}\)
\(\Rightarrow\frac{2011}{2012}< \frac{2013}{2014}\)
Mk so sánh khoảng cách của các số đến 1.
\(1-\frac{2011}{2012}=\frac{1}{2012}\)
\(1-\frac{2013}{2014}=\frac{1}{2014}\)
Vì: \(2012< 2014\) nên \(\frac{2011}{2012}< \frac{2013}{2014}\)
72 + 36 * 2 + 24 * 3 + 18 * 4 + 12 + 6 + 168
= 72 + 72 + 72 + 72 + 12 + 6 + 168
= 72 * 4 + 12 + 6 + 168
= 288 + 12 + 6 + 168
= 474

\(C=\frac{2}{1.7}+\frac{2}{7.13}+...+\frac{2}{601.607}\)
\(C=\frac{2}{6}.\left(1-\frac{1}{7}+\frac{1}{7}-\frac{1}{13}+...+\frac{1}{601}-\frac{1}{607}\right)\)
\(C=\frac{1}{3}.\left(1-\frac{1}{607}\right)\)
\(C=\frac{1}{3}.\frac{606}{607}\)
\(C=\frac{202}{607}\)
Dấu " ." là dấu nhân
=\(\frac{24}{100}+\frac{8}{100}+\frac{59}{100}+\frac{9}{100}\)
=1
\(\frac{12}{50}+8\%+\frac{59}{100}+0,09\)
\(=\frac{24}{100}+\frac{8}{100}+\frac{59}{100}+\frac{9}{100}\)
\(=\frac{24+8+59+9}{100}\)
\(=\frac{100}{100}\)
\(=1\)
