\(\frac{23.5-23}{4-27}\)=\(\frac{23.\left(5-1\right)}{-23}\)=\(\frac{92}{-23}\)
\(\frac{23.5-23}{4-27}\)=\(\frac{23.\left(5-1\right)}{-23}\)=\(\frac{92}{-23}\)
tìm số x biết
a) \(\frac{7}{9}:\left(2+\frac{3}{4}x\right)+\frac{5}{9}=\frac{23}{27}\) b) \(\frac{-2}{3}.x+\frac{1}{5}=\frac{3}{10}\) c) \(\left|x\right|-\frac{3}{4}=\frac{5}{3}\)
Rút gọn :
A= \(\frac{12^{10}+6^9.4^6}{15.2^{18}.9^4-2^{19}-27^3}\)
Rút gọn :
P = \(\frac{12^{10}+6^9.4^6}{15.2^{18}.9^4-2^{19}-27^3}\)
Rút gọn phân số sau :
\(\frac{2^3.3^3.5^3.7.8}{3.2^4.5^3.14}\)
Rút gọn biểu thức sau:
\(P=\frac{12^{10}+6^9.4^6}{15.2^{18}.9^4-2^{19}-27^3}\)
Mình cần gấp các bạn giúp nha!
\(\frac{\left(2.4.6.....2016\right).\left(2.4.6.....2016\right)}{\left(1.3.5.....2015\right).\left(3.5.7.....2017\right)}\) rút gọn bằng gì vậy?
rút gọn
1+3^2+3^3+3^4+3^5.+.....+3^20
Rút gọn :
a) \(\frac{3600-75}{8400-105}\)
b) \(\frac{9^{14}.25^5.8^2}{18^{12}.625^3.24^3}\)
c) C = \(\frac{1+3+5+...+19}{21+23+25+...+39}\)
\(\left(3,5-70,84:23+4-3,375.\frac{4}{9}\right):0,78\)
