\(\left(\frac{25}{4}\right)^5\cdot\frac{2}{5}+\frac{-5}{4}\)
\(\frac{25}{4}^5=9536,743164\)
\(\Rightarrow\left(\frac{25}{4}\right)^5\cdot\frac{2}{5}+\frac{-5}{4}\)
\(=3814,697266+\frac{-5}{4}\)
\(=3813,447266\)
\(\left(\frac{25}{4}\right)^5.\frac{2}{5}+\frac{-5}{4}=\frac{\left(5^2\right)^5}{\left(2^2\right)^5}.\frac{2}{5}+-\frac{5}{2^2}\)
\(=\frac{5^{10}}{2^{10}}.\frac{2}{5}+\frac{-5}{2^2}\)
\(=\frac{5.5^9.2}{2.2^9.5}+-\frac{5}{2^2}\)
\(=\frac{5^9}{2^9}+-\frac{5}{2^2}\)
đến đây thì mk ko pik lm nữa!ahihi nếu bn nào nghĩ đc cách tính thuận tiện hơn thì góp ý giùm nha!!!
