là dấu nhân nha

 ( 4^5.9^4+2.6^9) : (2^10.3^8-6^8.2) = \(\frac{4^5.9^4+2.6^9}{2^{10}.3^8-6^8.2}=\frac{\left(2^2\right)^5.\left(3^2\right)^4+2.6^9}{2^{10}.3^8-6^8.2}\)

= \(\frac{2^{10}.3^8+2.6^9}{2^{10}.3^8-6^8.2}=\frac{2\left(6^8.8\right)}{2.6^8}=\frac{6^8.8}{6^8}=8\)

Ết nha bạn ( eight : 8 )

\(A=\dfrac{4^5.9^4-2.6^9}{2^{10}.3^8+6^8.20}\)
\(=\dfrac{2^{10}.3^8-2.2^9.3^9}{2^{10}.3^8+2^8.3^8.2^2.5}\)
\(=\dfrac{2^{10}.3^8-2^{10}.3^9}{2^{10}.3^8+2^{10}.3^8.5}\)
\(=\dfrac{2^{10}.3^8\left(1-3\right)}{2^{10}.3^8\left(1+5\right)}\)
\(=-\dfrac{2}{6}=-\dfrac{1}{3}\)

\(=\dfrac{\left(2^2\right)^5.\left(3^2\right)^4-2.3^9.2^9}{2^{10}.3^8+2^8.3^8.2^2.5}=\dfrac{2^{10}.3^8-2^{10}.3^9}{2^{10}.3^8+2^{10}.3^8.5}=\dfrac{2^{10}.3^8\left(1-3\right)}{2^{10}.3^8\left(1+5\right)}=\dfrac{-2}{6}=-\dfrac{1}{3}\)

\(A=\left\{\left[\left(\frac{-1}{2}+\frac{-1}{9}\right)-\frac{7}{18}\right]+\left(\frac{3}{5}+\frac{4}{35}+\frac{2}{7}\right)+\frac{1}{127}\right\}\)

\(\Rightarrow A=\left\{\left[\frac{-11}{18}-\frac{7}{18}\right]+1+\frac{1}{127}\right\}\)

\(A=\left(-1\right)+1+\frac{1}{127}\)

\(A=0+\frac{1}{127}\)

\(A=\frac{1}{127}\)

-10/11

\(M=\left(\dfrac{4}{9}-\dfrac{7}{11}\right)-\dfrac{4}{9}-\dfrac{3}{11}\)

\(=\dfrac{4}{9}-\dfrac{7}{11}-\dfrac{4}{9}-\dfrac{3}{11}\)

\(=\left(\dfrac{4}{9}-\dfrac{4}{9}\right)-\left(\dfrac{7}{11}+\dfrac{3}{11}\right)\)

\(=0-\dfrac{10}{11}=-\dfrac{10}{11}\)

lol

boss đang gấp mọe như b**

= 13/30

\(M=\left(\dfrac{4}{9}-\dfrac{7}{11}\right)-\dfrac{4}{9}-\dfrac{3}{9}\)

\(=\dfrac{4}{9}-\dfrac{7}{11}-\dfrac{7}{9}\)

\(=-\dfrac{1}{3}-\dfrac{7}{11}=-\dfrac{32}{33}\)

kết quả bằng 1 đó bạn

\(96-4:\left[\left(11-9\right)^5:\left(7-5\right)^3\right]\)

\(96-4:\left[2^5:2^3\right]=96-4:\left[2^2\right]=96-4:4=96-1=95\)

96 - 4: [ (11 - 9)⁵ : ( 7 - 5)³ ] 

96 - 4 : [ 2⁵ : 2³ ]

96 - 4: 2²

= 96 - 4: 4

= 96 - 1

= 95
