Question

Tính nhanh :  B = 2^10.13 + 2^10.65 / 2^8.104.

Answer 1

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

Answer 2

B = \(\frac{2^{10}.13-2^{10}.65}{2^8.104}=\frac{2^{10}.\left(13+65\right)}{2^{8.104}}=\frac{2^{10}.78}{2^8.104}=\frac{2^2.39}{52}=\frac{2^2.39}{2^2.13}=\frac{39}{13}=3\)

Answer 3

2¹⁰.13+2¹⁰.65/2⁸.104=2¹⁰.(13+65)/2⁸.104=2¹⁰.78/2¹⁰.26=78/26=3
