\(\dfrac{32.9.11}{12.24.22}\) = \(\dfrac{8.4.3.3.11}{3.4.8.3.11.2}\) = \(\dfrac{1}{2}\)
\(\dfrac{32.9.11}{12.24.22}=\dfrac{8.4.3.3.11}{3.4.8.3.11.2}=\dfrac{1}{2}\)
b: \(\dfrac{50}{125}=\dfrac{50:25}{125:25}=\dfrac{2}{5}\)
\(\dfrac{-8}{12}=\dfrac{-8:4}{12:4}=\dfrac{-2}{3}\\ \dfrac{15}{-60}=\dfrac{15:15}{-60:15}=\dfrac{1}{-4}\\ \dfrac{-16}{-72}=\dfrac{-16:\left(-8\right)}{-72:\left(-8\right)}=\dfrac{2}{9}\\ \dfrac{35}{14.15}=\dfrac{5.7}{7.2.5.3}=\dfrac{1}{2.3}=\dfrac{1}{6}\)
\(\dfrac{60}{72}=\dfrac{60:12}{72:12}=\dfrac{5}{6}\\ \dfrac{70}{95}=\dfrac{70:5}{95:5}=\dfrac{14}{19}\\ \dfrac{150}{360}=\dfrac{150:30}{360:30}=\dfrac{5}{12}\)
\(\frac{11.4-11}{2-13}\)
\(=\frac{11\left(4-1\right)}{-11}\)
\(=\frac{3}{-1}\)
\(=-3\)
gọi A = 224.39.62=224.39.22.32=226.311
B = 22.121115 - 166.312 = 22.222.311.3.5 - 248.312 = 244.312.5 - 248.312 = (244.312)(5 - 24)
=>\(\frac{A}{B}\)= \(\frac{2^{26}.3^{11}}{\left(2^{44}.3^{12}\right)\left(5-2^4\right)}\)= \(\frac{1.\left(2^{26}.3^{11}\right)}{\left(2^{18}.3\right).\left(2^{26}.3^{11}\right).\left(-11\right)}\)= \(\frac{1}{\left(2^{18}.3\right).\left(-11\right)}\)
nhớ k cho mik nha
\(\dfrac{72\times75}{125\times108}\) = \(\dfrac{36\times2\times25\times3}{25\times5\times36\times3}\) = \(\dfrac{2}{5}\)
