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.
\(A=\frac{2^{10}\cdot13+2^{10}\cdot65}{2^8\cdot100}\)
\(=\frac{2^{10}\cdot13\left(1+5\right)}{2^8\cdot2^2\cdot5^2}\)
\(=\frac{2^{10}\cdot13\cdot6}{2^{10}\cdot5^2}\)
\(=\frac{13\cdot6}{25}\)
\(=\frac{78}{25}\)
