Các kết quả bạn ghi đều nối kết quả với nhau nên mình không cần tính , chỉ cần tính ở đoạn 1024 cộng 1024 thôi !

Đúng rồi

A=1+4+16+64+256+1024 =1365

bằng 1365 nha

=(1+4)+(16+1024)+(64+256)

=5+1040+320

=5+1360

=1365

k mun suy nghi nhiu thi lam nhu z

64^x.16^x=256¹²:1024

1024^x=4⁴³

4^5x=4⁴³

5x=43

x=8,6

\(64^x.16^x=256^{12}:1024\)

\(\Rightarrow\) \(\left(4^3\right)^x.\left(4^2\right)^x=\left(4^4\right)^{12}:4^5\)

\(\Rightarrow\) \(4^{3x}.4^{2x}=4^{48}:4^5\)

\(\Rightarrow\) \(4^{3x+2x}=4^{43}\)

\(\Rightarrow\) \(3x+2x=43\)

\(\Rightarrow\) \(\left(3+2\right)x=43\)

\(\Rightarrow\) \(5x=43\)

\(\Rightarrow\) \(x=\frac{43}{5}\)

Đặt A = 1/2 + 1/4 + 1/8 + 1/16 + 1/32 + 1/64 + 1/128 + 1/256

=> 2A = 1 + 1/2 + 1/4 + 1/8 + 1/16 + 1/32 + 1/64 + 1/128

=> 2A - A = (1 + 1/2 + 1/4 + 1/8 + 1/16 + 1/32 + 1/64 + 1/128) -                                     (1/2 + 1/4 + 1/8 + 1/16 + 1/32 + 1/64 + 1/128 + 1/256)

=> A = 1 - 1/256

=> A = 255/256

Vậy: ...
