\(\frac{10^4.81-16.15^2}{4^4.675}\)

= \(\frac{2^4.5^4.3^4-2^4.3^2.5^2}{4^4.3^3.5^2}\)

= \(\frac{2^4.5^2.3^4-2^4.3^2.5^2}{2^8.3^3.5^2}\)= \(\frac{2^4.5^2.3^2\left(3^2-1\right)}{2^8.3^3.5^2}\)= \(\frac{8}{2^4.3}=\frac{1}{6}\)

mấy bài khó còn làm dc ko lẽ ko làm dc bài này hay quân kiến thức cũ vậy bn

\(\frac{10^4.81-16.15^2}{4^4.675}=\frac{2^4.5^4.3^4-2^4.3^2.5^2}{2^8.3^3.5^2}\)

\(=\frac{2^4.3^2.5^2.\left(5^2.3^2-1\right)}{2^8.3^3.5^2}\)

\(=\frac{25.9-1}{2^4.3}=\frac{225-1}{16.3}=\frac{224}{48}=\frac{14}{3}\)

\(\frac{10^4.81-16.15^2}{4^4.675}=\frac{\left(2.5\right)^4.3^4-2^4\left(3.5\right)^2}{2^8.5^2.3^3}=\frac{2^4.3^2.5^2\left(5^2.3^2-1\right)}{2^8.5^2.3^3}=\frac{255-1}{16.3}=\frac{14}{3}\)

\(\frac{10^4.81-16.15^2}{4^4.675}=\frac{10^4.3^4-4^2.15^2}{4^4.5^4}=\frac{30^4-60^2}{20^4}=\frac{900^2-60^2}{400^2}=\frac{20^2\left(45^2-3^2\right)}{20^2.2^2}=\frac{2016}{4}=504\)

love forever and only one sai rùi kìa

675= 5^4 cơ mà

\(A=\frac{10^4\cdot81-16\cdot15^2}{4^4\cdot675}\)

\(=\frac{2^4\cdot5^4\cdot3^3-2^4\cdot3^2\cdot5^2}{2^8\cdot3^3\cdot5^2}\)

\(=\frac{2^4\cdot5^2\cdot3\left(5^2\cdot3-3\right)}{2^8\cdot3^3\cdot5^2}\)

\(=\frac{5^2\cdot3-3}{2^4\cdot3^2}\)

\(=\frac{3\cdot\left(5^2-1\right)}{2^4\cdot3^2}=\frac{24}{48}=\frac{1}{2}\)

các bạn ơi 500 nhân 687= bao nhiêu

=14/3 nha Có cần cách làm ko?

10⁴.81 - 16,15²  /  4⁴,675 = 9739,9875/256,675

chắc em làm sai , vì em mới học lớp 5 , tỷ lệ đúng chắc chỉ là 1%

\(\frac{10^4.81-16.15^2}{4^4.675}=\frac{\left(2.5\right)^4.3^4-2^4\left(3.5\right)^2}{2^8.5^2.3^3}=\frac{2^4.3^2.5^2\left(5^2.3^2-1\right)}{2^8.5^2.3^3}=\frac{255-1}{16.3}=\frac{14}{3}\)

\(A=\frac{10^4.81-16.15^2}{4^4.675}=\frac{\left(2.5\right)^4.3^4-2^4.\left(3.5\right)^2}{\left(2^2\right)^4.3^3.5^2}=\frac{2^4.5^4.3^4-2^4.3^2.5^2}{2^8.3^35^2}=\frac{2^4.5^4.3}{2^4.3}=5^4=625\)

\(=\dfrac{2^4\cdot5^4\cdot3^4-2^4\cdot3^2\cdot5^2}{2^8\cdot3^3\cdot5^2}=\dfrac{2^4\cdot3^2\cdot5^2\left(5^2\cdot3^2-1\right)}{2^8\cdot3^3\cdot5^2}\)

\(=\dfrac{1}{16}\cdot\dfrac{1}{3}\cdot\dfrac{224}{1}=\dfrac{224}{48}=\dfrac{14}{3}\)

\(\dfrac{10^4.81-16.15^2}{4^4.675}\)

\(=\dfrac{2^4.5^4.9^2-2^4.3^2.5^2}{2^8.5^4}\)

\(=\dfrac{1.25.9^2-1.3^2.1}{1.1}=1.25.9^2-1.3^2.1\)

\(=1899\)
