\(\frac{6^3+3.6^2+3}{-13}\)
\(=\frac{216+108+27}{-13}\)
\(=\frac{351}{-13}\)
\(=-27\)
\(\frac{6^3+3\cdot6^2+3^3}{-13}=\frac{216+108+27}{-13}\)
\(=\frac{351}{-13}=\frac{27\cdot13}{-13}=-27\)
\(\frac{6^3+3\cdot6^2+3^3}{-13}\)
đổi tik nha? ^-^
a) \(\frac{\left(-1\right)^3}{15}+\left(-\frac{2}{3}\right):2\frac{2}{3}-\left|-\frac{5}{6}\right|\)
b) \(1\frac{5}{13}-0,\left(3\right)-\left(1\frac{4}{9}+\frac{18}{13}-\frac{1}{3}\right)\)
c) \(\left|97\frac{2}{3}-125\frac{3}{5}\right|+97\frac{2}{5}-125\frac{1}{3}\)
d) \(\frac{2\cdot6^9-2^5\cdot18^4}{2^2\cdot6^8}\)
Tính:
a,\(\frac{4^2\cdot4^3}{2^{10}}\)
b,\(\frac{0,6^5}{0,2^6}\)
c,\(\frac{2^7\cdot9^3}{6^5\cdot8^2}\)
d,\(\frac{6^3+3\cdot6^2+3^3}{-13}\)
Rút gọn
a) B=\(\frac{2^7\cdot9^3}{6^5\cdot8^2}\)
b) C = \(\frac{6^3+3\cdot6^2+3^3}{-13}\)
c) M = \(\frac{2:6^{18}-4^{10}\cdot98}{4^{10}\cdot3^{16}+6^{12}\cdot200}\)
\(\frac{7}{3\cdot4}-\frac{9}{4\cdot5}+\frac{11}{5\cdot6}-\frac{13}{6\cdot7}+\frac{15}{7\cdot8}-\frac{17}{8\cdot9}+\frac{19}{9\cdot10}\)
rút gọn biểu thức
a) \(\frac{20^5\cdot5^{10}}{\left(4\cdot25\right)^5}\)b)\(\frac{6^3+3\cdot6^2+3^3}{-13}\)c)\(\frac{125^{12}}{5^{13}\cdot25^{11}}\)d)\(\left(2^{-1}+3^{-1}\right):\left(2^{-1}-3^{-1}\right)+\left(2^{-1}\cdot2^0\right)\cdot2^3\)
e)\(\frac{81^{11}\cdot3^{17}}{27^{10}\cdot9^{15}}\)
Tìm x, biết
\(\left(\frac{1}{2}-\frac{1}{3}\right)\cdot6^x+1+6^x+1=7\cdot6^9\)
x=\(\frac{3^{^2}\cdot6^3\cdot9^6}{2^3\cdot3^{15}}\)
Tìm x biết:
\(\left(\frac{1}{2}-\frac{1}{3}\right)\cdot6^{x+1}+6^{x+1}=7\cdot6^9\)
