`[2^15. 9^4]/[6^3. 8^3]`
`=[2^15 .(3^2)^4]/[(2.3)^3.(2^3)^3]`
`=[2^15 .3^8]/[2^3 .3^3 .2^9]`
`=[2^15 .3^8]/[3^3 . 2^12]`
`=[2^3 . 3^5]/[1.1]`
`=1944`
Tính:
a) \(\dfrac{4^5.9^4-2.6^9}{2^{10}.3^8+6^8.20}\)
b) T=\(\dfrac{5^{16}.27^7}{125^5.9^{11}}\)
\(\dfrac{4^5.9^4-2.6^9}{2^{10}.3^8+6^8.20}\)
Tính: A=\(\dfrac{4^5.9^4-2.6^9}{2^{10}.3^8+6^8.20}\)

b)8^10+4^10/8^4+4^11
\(^{\frac{4^5.9^4-2.6^9}{2^{10}.3^8+6^8.20}}\)
trả lời nhanh hộ mình cái đang gấp
(-0,25)^-5.9^4.(-2)^-3 - 2^-2.6^9/2^9.3^6 +6^6.40
Tìm x biết
a) \(\frac{x-1}{21}=\frac{3}{x+1}\)
b)\(\frac{7}{x}+\frac{4}{5.9}+\frac{4}{9.13}+...+\frac{4}{41.45}=\frac{29}{45}\)
\(\dfrac{4^5.9^4}{8^3.27^3}\);\(\dfrac{4^{20}.3^{35}}{2^{37}.27^{12}}\)\(;\dfrac{5^4.20^4}{25^5.4^5};\dfrac{2^{15}.9^4}{6^6.8^3}\)
