nhập máy tính cầm tay:kết quả là: 32448

Nhớ kick mình nhé coi không mà không kick là thằng khùng

dấu chấm là nhân phải không bạn ?

2¹⁰x13+2¹⁰x65

=2¹⁰x(13+65)

=2¹⁰x78

=79872

a) = 2\(^{10}\).( 13+65)

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

=64.78

=4992

b) =256.104

=26624

\(\frac{2^{10}.13+2^{10}.65}{2^8.104}\) = \(\frac{2^{10}.\left(13+65\right)}{2^8.2^3.13}\) 

= \(\frac{2^{10}.78}{2^{11}.13}\) = \(\frac{2^{10}.2.3.13}{2^{11}.13}=\frac{2^{11}.3.13}{2^{11}.13}=3\)

\(\dfrac{2^{10}\cdot13+2^{10}\cdot65}{2^8\cdot104}=\dfrac{2^{10}\cdot13\cdot6}{2^8\cdot2^3\cdot13}=3\)

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

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

= \(\dfrac{2^2.78}{104}\)

= \(\dfrac{312}{104}\)

= 3
@Lê Hồ Duy Quang

\(\dfrac{2^{10}\cdot13+2^{10}\cdot65}{2^8\cdot104}=\dfrac{2^{10}\cdot\left(13+65\right)}{2^8\cdot104}=\dfrac{2^{10}\cdot78}{2^8\cdot104}=\dfrac{2^2\cdot3}{4}=3\)

2^10 . ( 13 + 65 ) / 2^8 . 104

2^10 . 78 / 2^8 . 104

= 2^8 . 2^2 . 78 / 2^8 . 104

= 2^2 . 78 / 104

= 4 . 78 / 104

= 78 / 26

= 3

Chúc bạn học tốt
