\(=\dfrac{5^3\cdot2^3+2\cdot5^3+5^3}{55}=\dfrac{5^3\left(2^3+2+1\right)}{55}=5^2=25\)

theo máy tính kết quả là: \(\frac{13775}{11}\)

tự làm đi dễ mà

10\(^3\) + 2. 5\(^3\) + \(\frac{5^3}{55}\)

= 1000 + 2. 125 + \(\frac{125}{55}\)

= 1000 + 250 + \(\frac{25}{11}\)

= 1250 + \(\frac{25}{11}\)

= 1250\(\frac{25}{11}\) =\(\frac{\text{ 89575}}{88}\)

\(\dfrac{10^3+2.5^3+5^3}{55}=\dfrac{\left(2.5\right)^3+2.5^3+5^3}{55}=\dfrac{2.5^3+2.5^3+5^3}{55}=\dfrac{5^3\left(2+2+1\right)}{55}=\dfrac{5^2.5}{11}=\dfrac{5^3}{11}=\dfrac{125}{11}\)

\(\dfrac{10^3+2.5^3+5^3}{55}=\dfrac{\left(2.5\right)^3+2.5^3+5^3}{55}\)

\(\Rightarrow\)\(\dfrac{5^3\left(2+2+2\right)}{55}\)=\(\dfrac{5^3}{11}\)=\(\dfrac{125}{11}\)

\(=\dfrac{1000+127+125}{55}=\dfrac{1252}{55}\)

\(\frac{10^3+2.5^3+5^3}{55}\)

\(=\frac{\left(2.5\right)^3+2.5^3+5^3}{5.11}\)

=\(\frac{2^3.5^3+2.5^3+5^3}{5.11}\)

=\(\frac{5^3.\left(2^3+2+1\right)}{5.11}\)

=\(\frac{5^3.\left(8+2+1\right)}{5.11}\)

=\(\frac{5^3.11}{5.11}\)

=\(5^2\)

=25

Chúc bn học tốt !

= 25 nha bạn 

các bạn tick mình cho tròn 220 điểm hỏi đáp với

\(=\frac{5^3.\left(2^3+2+1\right)}{55}=\frac{5^2.5.11}{5.11}=5^2=25\)
