\(\frac{4^7.3^4.9^6}{6^{13}}\)
sao ko a tl
\(\frac{4^7.3^4.9^6}{6^{13}}\)
Ừm đáp án này:
2^14 . 3^4 . 9^6 / 6^13
= (2^2)^7 . 3^4 . (3^2)6 / (2.3)^13
= 2^14 . 3^4 . 3^12 / 2^13 . 3^13
= 2 . 3^3 . 1 / 1 . 1 . 1
= 2 . 27
= 54
Bạn ơi dấu / thay cho dấu bằng còn ^ thay cho mũ nhé
Hơi rối mắt tí :3
\(\frac{4^7.3^4.9^6}{6^{13}}\) tính hợp lí
\(\frac{4^7.3^4.9^6}{6^{13}}=\frac{\left(2^2\right)^7.3^4.\left(3^2\right)^6}{\left(2.3\right)^{13}}=\frac{2^{14}.3^4.3^{12}}{2^{13}.3^{13}}=\frac{2.2^{13}.3^{13}.3^3}{2^{13}.3^{13}}=2.3^3=2.27=54\)
ko pt mà mấy bạn cứ xông zô trả lời,phí giấy của olm quá

a)4^7.3^4.9^6:6^13
b2^3.3^2-5^16:25^7
ai nhanh mk sẽ tick
a, \(4^7.3^4.9^6:6^{13}\)
\(=\left(2^{14}.3^4.3^{12}\right):\left(2^{13}.3^{13}\right)\)
\(=2^{14}:2^{13}.3^{16}:3^{13}\)
\(=2.3^3=54\)
b, \(2^3.3^2-5^{16}:25^7\)
\(=72-5^{16}:5^{14}\)
\(=72-5^2=47\)

- Các bạn giúp mình tính gái trị các câu nhan !! Làm từng bước nhé ! Đúng mik tk
a, \(\frac{4^7.3^4.9^6}{6^{13}}\) b, \(\frac{5^{10}.13+5^{10}.65}{5^8.104}\) c, \(\frac{2^{10}.55+2^{10}.26}{2^8.27}\)
4^9.36+64^4/16^4.100
4^6.3^4.9^5/6^12
ai tl đúg mk tick cho nha
B = 4^9.36+64^4
16^4.100
B = 2^20.(9+16)
2^18.5^2
B = 2^20.5^2
2^18.5^2
B = 2^2
B = 4
D = 4^6.3^4.9^5
6^12
D = 2^12.3^4.9^5
2^12.3^12
D = 2^12.3^14
2^12.3^12
D = 3^2
D = 9
\(\frac{4^9.36+64^4}{16^4.100}=\frac{4^{10}\left(9+8\right)}{4^{10}.25}=\frac{17}{25}\)

Rút gọn các phân số sau:
a)\(\dfrac{11.8-11.3}{17-6}\) ; b)\(\dfrac{24-12.13}{12+4.9}\); c)\(\dfrac{7.6-7.4}{7.3}\); d)\(\dfrac{7}{9.10^2-2.10^2}\)
a) \(\dfrac{11\cdot8-11\cdot3}{17-6}\)
\(=\dfrac{11\cdot\left(8-3\right)}{11}=5\)
b) \(\dfrac{24-12\cdot13}{12+4\cdot9}\)
\(=\dfrac{12\cdot\left(2-13\right)}{12\left(1+3\right)}=\dfrac{-11}{4}\)
