Question

(x+1/2) + (x +1/4) +( x + 1/8 ) + (x + 1/16)= 1

các bạn giải rõ ràng nha

 

Answer 1

(x+1/2)+(x+1/4)+(x+1/8)+(x+1/16)=1

<=>(x+x+x+x)+(1/2+1/4+1/8+1/16)=1

<=>4x+15/16=1

=>4x=1-15/16=1/16

=>x=1/16:4

=>x=1/64

Answer 2

4x+15/16=1

4x=1/16

1x=1/16/4

x=1/64

Answer 4

 \(\left(x+\frac{1}{2}\right)+\left(x+\frac{1}{4}\right)+\left(x+\frac{1}{8}\right)+\left(x+\frac{1}{16}\right)=1\)

\(x+\frac{1}{2}+x+\frac{1}{4}+x+\frac{1}{8}+x+\frac{1}{16}=1\)

\(\left(x+x+x+x\right)+\left(\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}\right)=1\)

\(4x+\frac{15}{16}=1\)

\(4x=1-\frac{15}{16}=\frac{1}{16}\)

\(x=\frac{1}{16}:4=\frac{1}{64}\)
