\(=\left(5+5\right)+\left(8+2\right)+\left(6+4\right)+\left(8+1+1\right)+7\)
\(=10+10+10+10+7\)
\(=47\)
5 + 5 + 8 + 2 + 6 + 4 + 8 + 1 + 1 + 7 = 47
k cho minh cac ban nhe
5 + 5 + 8 + 2 + 6 + 4 + 8 + 1 + 1 + 7
= 5 x 2 + 8 x 2 + 1 x 2 + 2 + 4 + 6 + 7
= 10 + 16 + 2 x 2 + 4 + 6 + 7
= 26 + 4 x 2 + 6 + 7
= 26 + 8 + 6 + 7
= 34 + 7 + 8
= 41 + 8
=49.
