thế này thì máy tính cũng kiệt luôn !

256 x 6=512 x 3

512 x 3=256 x 6

999 x 2>1000

512 x 5>1024

1024<512 x 5

1024=512 x 2

512=256 x 2

256=128 x 2

128=64 x 2

64=32 x 2

32=16 x 2

Đúng rồi

\(=2^{110}\cdot5^3\cdot2^6\cdot5^{2021}=2^{116}\cdot5^{2024}\)

64 . 4^x = 16⁸

<=> 4³. 4^x = 4¹⁶

=> 3 + x = 16

<=> x = 13

Vậy x = 13

2^x.16² = 1024

<=> 2^x. 2⁸ = 2¹⁰

=> x + 8 = 10

<=> x = 2

Vậy x = 2

64^x.16^x=256¹²:1024

1024^x=4⁴³

4^5x=4⁴³

5x=43

x=8,6

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

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

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

\(\Rightarrow\) \(4^{3x+2x}=4^{43}\)

\(\Rightarrow\) \(3x+2x=43\)

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

\(\Rightarrow\) \(5x=43\)

\(\Rightarrow\) \(x=\frac{43}{5}\)

64^x.16^x=256¹²:1024

1024^x=4⁴³

4^5x=4⁴³

5x=43

x=8,6

x^20-x=0

x(x^19-1)=0

x= 0 

hoặc x ^ 19 =1

x = 0 hoặc x= 1
