\(\frac{27^6.81^8.3^9}{3^7.3^6.3^{15}}=\frac{\left(3^3\right)^6.\left(3^4\right)^8.3^9}{3^7.3^6.3^{15}}=\frac{3^{18}.3^{32}.3^9}{3^7.3^6.3^{15}}\)
= \(\frac{3^{59}}{3^{28}}=3^{59}:3^{28}=3^{31}\)
rút gọn : m = 2^7.3^5+2^4.3^9 phần 2^6.3^5+2^3 .3^9
Giúp mình vs ạ
\(\frac{2^{15}.2+3}{8^6.3^9}\)RÚT GỌN
Rút gọn phân số: M=\(\frac{9^4.27^5.3^6.3^4}{3^8.81^4.234.8^2}\)
M = \(\frac{9^4.27^5.3^6.3^4}{3^8.81^4.234.8^2}\)
*Rút gọn nhé
Rút gọn:
a,\(\frac{15.\left(1352-41\right)}{\left(1352-41\right)\left(150-15\right)}\)
b,\(\frac{2^{10}.6^{15}+3^{14}.15.4^{13}}{2^{18}.18^7.3^3+3^{15}.2^{25}}\)
5.\(3^x=8.3^1+7.3^9\)
Rút gọn
