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)
=>\(\frac{A}{B}\)= \(\frac{2^{26}.3^{11}}{\left(2^{44}.3^{12}\right)\left(5-2^4\right)}\)= \(\frac{1.\left(2^{26}.3^{11}\right)}{\left(2^{18}.3\right).\left(2^{26}.3^{11}\right).\left(-11\right)}\)= \(\frac{1}{\left(2^{18}.3\right).\left(-11\right)}\)
