3^12.(3^4)^11/(3^3)^10.(3^2)^15=3^12.3^44/3^30.3^30=3^56/3^30
=3^17.9^22/3^30.9^15=9^7/3^13=3^14/3^13=3^1=3
giùm nhé bạn
\(\frac{3^{17}.81^{11}}{27^{10}.9^{15}}+\frac{9^2.2^{11}}{16^2.6^3}\)
tính
\(\frac{2^{15}.9^4}{6^3.8^3}\)
\(\frac{81^{11}.3^{17}}{27^{10}.9^{15}}\)
Rút gọn:
\(\frac{3^{17}.81^{11}}{27^{10}.9^{15}}\)
Tính:
a) \(\left(-0,125\right)^3.80^4\)
b) \(\frac{81^{11}.3^{17}}{27^{10}.9^{15}}\)
Tính
a)(0,25)3.32
b) (-0,125)3.804
c)\(\frac{8^2.4^5}{2^{20}}\)
d)\(\frac{81^{11}.3^{17}}{27^{10}.9^{15}}\)
1/2x + 2/9 = 7/6
317 × 8111/ 2710 × 915
2/5x - 1/3 = 2/3
/=\(\frac{ }{ }\)
\(\frac{81^{11}\cdot3^{17}}{27^{10}\cdot9^{15}}\)
\(A=\frac{\frac{1}{11}-\frac{1}{13}-\frac{1}{17}}{\frac{5}{11}-\frac{5}{13}-\frac{5}{17}}+\frac{\frac{-3}{3}-\frac{2}{9}-\frac{2}{27}+\frac{2}{81}}{\frac{7}{3}-\frac{7}{9}-\frac{7}{27}+\frac{7}{81}}\)
Tính hợp lí
a/(0,25)3 .32
b/ (-0,125)3 .804
c/ \(\frac{8^2.4^5}{2^{20}}\)
d/ \(\frac{81^{11}.3^{17}}{27^{10}.9^{15}}\)
