B = \(\frac{2^{10}.13+2^{10}.65}{2^8.104}=\frac{2^{10}.\left(13+65\right)}{2^8.104}=\frac{2^{10}.78}{2^8.104}\)
B = \(\frac{2^2.39}{52}=\frac{2^2.39}{2^2.13}\)
B = \(\frac{39}{13}\)
B = 3
B = \(\frac{2^{10}.13-2^{10}.65}{2^8.104}=\frac{2^{10}.\left(13+65\right)}{2^{8.104}}=\frac{2^{10}.78}{2^8.104}=\frac{2^2.39}{52}=\frac{2^2.39}{2^2.13}=\frac{39}{13}=3\)
= 2^10 . ( 13 + 65 ) / 2^8 . 104
= 2^10 . 78 / 2^8 . 104
= 2 . 2 . 2^8 . 78 / 2^8 . 104
= 2^8 . 312 / 104
= 3
\(\frac{2^{10}.13+2^{10}.65}{2^8.104}=\frac{2^{10}.13+2^{10}.5.13}{2^8.2^3.13}=\frac{2^{10}.13\left(1+5\right)}{2^{11}.13}=\frac{2^{10}.13.2.3}{2^{11}.13}=\frac{2^{11}.3.13}{2^{11}.13}=3\)
\(A=\frac{3^{10}.11+3^{10}.5}{3^9.2^4}=\frac{3^{10}.16}{3^9.16}=3\)
\(B=\frac{2^{10}.13+2^{10}.65}{2^8.104}=\frac{2^{10}.78}{2^8.104}=\frac{2^{10}.26.3}{2^8.2^2.26}=3\)
\(C=\frac{72^3.52^4}{108^4}=\frac{\left(3^2.2^3\right)^3.\left(13.2^2\right)^4}{\left(3^3.2^2\right)^4}=\frac{3^6.2^9.13^4.2^8}{3^{12}.2^8}=\frac{2^9.13^4}{3^6}\)
\(D=\frac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}=\frac{11.3^{29}-\left(3^2\right)^{15}}{2^2.3^{28}}=\frac{11.3^{29}-3^{30}}{2^2.3^{28}}=\frac{3^{29}\left(33-1\right)}{2^2.3^{28}}=\frac{3^{29}.2^5}{2^2.3^{28}}=3.8=24\)
Giải thích các bước giải:
A = (2¹⁰.13 + 2¹⁰.65)/2⁸.104
= (2¹⁰.13 + 2¹⁰.13.5)/2⁸.104
= 2¹⁰.13.(1 + 5)/2⁸.104
= 2².13.6/104
= 4.13.6/104
= 312/104
= 3
Vậy A = 3.
\(A=\frac{2^{10}\cdot13+2^{10}\cdot65}{2^8\cdot100}\)
\(=\frac{2^{10}\cdot13\left(1+5\right)}{2^8\cdot2^2\cdot5^2}\)
\(=\frac{2^{10}\cdot13\cdot6}{2^{10}\cdot5^2}\)
\(=\frac{13\cdot6}{25}\)
\(=\frac{78}{25}\)
210.13 + 210.65 = 210(13 + 65) = 210.78
28.104 = 28(26 + 25 + 23) = 214 + 213 + 211
= 3 nha !
k mik nhé
\(\frac{2^{10}.13+2^{10}.65}{2^8.104}=\frac{2^{10}.13+2^{10}.13.5}{2^8.2^3.13}\)
\(=\frac{2^{10}.13+2^{10}.13.5}{2^{11}.13}\)
\(=\frac{2^{10}.13\left(1+5\right)}{2^{11}.13}\)
\(=\frac{2^{10}.13.6}{2^{11}.13}\)
\(=\frac{2^{11}.13.3}{2^{11}.13}=3\)
T_i_c_k cho mình nha mơn bạn nhiều ^^
