5*5*5*5*5*5*5*5*5*5*55*5*5*5*5*5*5*55555555*5=?
cho minh hỏi nhé cái dấu sao đó co phải dấu nhân không ? nếu đó là dáu nhân thì bằng 5
5*5*5*5*5*5*5*5*5*5*5*5*5*5*5*5*0+1+55
5 x 5 x 5 x ... x 5 x 0 + 1 + 55 = 0 + 56 = 56

\(\dfrac{1}{55^2}\).\(5^4\).(-11)\(^2\) . \(55^5\) . (\(\dfrac{1}{5^2}\))\(^2\) : (\(5^3\) . \(11^6\)
\(\dfrac{1}{55^2}.5^4.\left(-11\right)^2.55^5.\left(\dfrac{1}{5^2}\right)^2:\left(5^3.11^6\right)\)
\(=\dfrac{5^4.11^2.5^5.11^5}{5^2.11^2}.\dfrac{1}{5^4.5^3.11^6}\)
\(=\dfrac{5^9.11^7}{5^9.11^8}=\dfrac{1}{11}\)
\(=\dfrac{1}{5^2\cdot11^2}\cdot5^4\cdot11^2\cdot55^5\cdot\left(\dfrac{1}{5}\right)^2\cdot\dfrac{1}{5^3\cdot11^6}\)
\(=5^2\cdot5^5\cdot11^5\cdot\dfrac{1}{5^2\cdot5^3\cdot11^6}\)
\(=\dfrac{11^5}{11^6}\cdot\dfrac{5^7}{5^5}=\dfrac{25}{11}\)
