\(\frac{2^{15}.9^4}{6^6.8^3}=\frac{2^{15}.\left(3^2\right)^4}{\left(2.3\right)^6.\left(2^3\right)^3}=\frac{2^{15}.3^8}{2^6.3^6.2^9}=\frac{2^{15}.3^8}{2^{15}.3^6}=\frac{3^8}{3^6}=3^2=9\)
Tính GT biểu thức:( tính nhanh )\(C=\frac{2^{15}\times9^4}{6^6\times8^3}\)
\(\frac{2^7\times9^3}{6^5\times8^2}\)
nhanh nha! thank you
*Tính:
\(\frac{2^5\times9^4}{6^6\times8^3}\)
\(\dfrac{4^{10}\times9^6+3^{12}\times8^5}{6^{13}\times4+2^{16}\times3^{12}}\)
Tính
a)\(A=\frac{\left(3\times2^{20}+7\times2^{19}\right)\times52}{\left(13\times8^4\right)^2}\)
b)\(B=\frac{2^{19}\times27^3+15\times4^9\times9^4}{6^9\times2^{10}+12^{10}}\)
1 tính :
a)\(\frac{2^{11}\times9^2}{3^5\times16^2}\); b) \(\frac{9^3\times27^2}{6^2\times3^{10}}\); c) \(\frac{27^{15}\times5^3\times8^4}{25^2\times81^{11}\times2^{11}}\)
1: Tính
a)\(45^{10}\times5^{20}\div75^{15}\)
b)\(2^{15}\times9^4\div6^6\times8^3\)
\(\frac{1}{3\times4}-\frac{1}{4\times5}-\frac{1}{5\times6}-\frac{1}{6\times7}-\frac{1}{7\times8}-\frac{1}{8\times9}-\frac{1}{9\times10}\)

giải chi tiết giúp mình nhé
