\(A=\frac{2^{10}.13+2^{10}.65}{2^8.104}=\frac{2^{10}.\left(13+65\right)}{2^8.104}=\frac{2^{10}.78}{2^8.104}=3\)

\(A=\frac{2^{10}.13+2^{10}.65}{2^8.104}=\frac{2^{10}\left(13+65\right)}{2^8.104}=\frac{2^{10}.78}{2^8.104}=\frac{2^2.78}{104}=\frac{2^2.2.39}{2^3.13}=\frac{2^3.39}{2^3.13}=3\)

\(A=\frac{2^{10}.13+2^{10}.65}{2^8.104}\)

\(=>A=\frac{2^{10}.\left(65+35\right)}{2^8.104}=\frac{2^{10}.78}{2^8.104}=3\)

A,\(\left(2^{10}.13+2^{10}.65\right):2^8.104\)

\(=78.2^{10}:2^8.104\)

\(=78.4.104\)

\(=56784\)

\(\frac{2^{10}.13+2^{10}.65}{2^8.104}\)

\(=\frac{2^{10}.\left(13+65\right)}{2^8.104}\)

\(=\frac{2^{10}.78}{2^8.104}\)

\(=\frac{2^8.2^2.78}{2^8.104}\)

\(=\frac{2^8.4.78}{2^8.104}\)

\(=\frac{2^8.312}{2^8.104}\)

\(=\frac{2^8.3.104}{2^8.104}=3\)

a, \(A=2015.20162016-2016.20152015\)

\(A=2015.\left(2016.10001\right)-2016.20152015\)

\(A=\left(2015.10001\right).2016-20152015.2016\)

\(A=20152015.2016-20152015.2016\)

\(A=0\)

Vậy A = 0

b, \(B=\left(3.4.2^{16}\right)^2\div11.2^{13}.4^{11}-16^9\)

\(B=3^2.2^4.2^{32}\div11.2^{13}.\left(2^2\right)^{11}-\left(2^4\right)^9\)

\(B=3^2.2^4.2^{32}\div11.2^{13}.2^{22}-2^{36}\)

\(B=3^2.2^{36}\div11.2^{35}-2^{36}\)

\(B=3^2.2^{35}.2\div11.2^{35}-2.2^{35}\)

\(B=3^2.2\div9=9.2\div9=2\)

Vậy B = 2

c, \(C=2^{10}.13+2^{10}.65\div2^8.104\)

\(C=2^{10}.\left(13+65\right)\div2^8.104\)

\(C=2^{10}.78\div2^8.104\)

\(C=2^{10}.39\div2^8.13\)

\(C=39\div13=3\)

Vậy C = 3

Đề bài câu c sai mk sửa nhé là 2⁸ ms tính đc k nó dư lắm !!!

2015.20162016-2016.20152015

=2015.2016.1001-2016.2015.1001

=0

\(\frac{2^{10}.13+2^{10}.65}{2^8.104}\)

\(=\frac{2^{10}.\left(13+65\right)}{2^8.104}\)

\(=\frac{2^8.2^2.81}{2^8.104}\)

\(=\frac{2^8.4.81}{2^8.104}\)

\(=\frac{2^8.324}{2^8.104}\)

\(=\frac{324}{104}\)

\(=\frac{81}{26}\)

\(\frac{2^{10}×13+2^{10}×65}{2^8×104}\)

\(=\frac{2^{10}×\left(13+65\right)}{2^8×104}\)

\(=\frac{2^8×2^2×81}{2^8×104}\)

\(=\frac{2^2×81}{104}\)

\(=\frac{324}{104}\)

\(=\frac{81}{26}\)

Làm cách này nhanh hơn nhé , bạn Xyz

thank bn nhưng 13+65 = 78 mà bn

\(2^{10}.13+2^{10}\)

=\(2^{10}.\left(13+1\right)\)

=2^10.14

=2^11.7

=14336

mk cũng ko bt

??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

khó hiểu bạn ơi
