Question

C=10/11+1/11.3/11+1/11.8/11 giải hộ vs ạ

Answer 1

\(C=\dfrac{10}{11}+\dfrac{1}{11}\cdot\dfrac{3}{11}+\dfrac{1}{11}\cdot\dfrac{8}{11}\)

\(=\dfrac{1}{11}\cdot\left(10+\dfrac{3}{11}+\dfrac{8}{11}\right)\)

\(=\dfrac{1}{11}\cdot\left(10+\dfrac{11}{11}\right)\)

\(=\dfrac{1}{11}\cdot\left(10+1\right)\)

\(=\dfrac{1}{11}\cdot11=1\)

Answer 2

`C=10/11+1/11*3/11+1/11*8/11`

`C=10/11+1/11*(3/11+8/11)`

`C=10/11+1/11*1`

`C=10/11+1/11`

`C=11/11`

`C=1`
