= 5^4.5^4.4^4/(5^2)^5.4^5
= 5^8.4^4/5^10.4^5
= 1/5^2.4 = 1/100
k mk nha
Ta có: \(\frac{5^4.20^4}{25^5.45}\)
=\(\frac{\left(5.20\right)^4}{\left(25.4\right)^5}\)
= \(\frac{100^4}{100^5}\)
=\(\frac{1}{100}\)
![](https://rs.olm.vn/images/avt/0.png?1311)
\(\frac{5^4.20^4}{25^5.4^5}=\frac{\left(5.20\right)^4}{\left(25.4\right)^5}=\frac{100^4}{100^5}=100^{-1}=\frac{1}{100}\)
![](https://rs.olm.vn/images/avt/0.png?1311)
\(\frac{5^4.20^4}{25^5.4^5}=\frac{5^4\left(1.15^4\right)}{\left(19^5.1\right).4^5}=\frac{5^4.15^4}{19^5.4^5}\)
\(\frac{5^4.20^4}{25^5.4^5}=\frac{\left(5.20\right)^4}{\left(25.4\right)^5}=\frac{100^4}{100^5}=\frac{1}{100}.\)
Chúc bạn học tốt!

54 . 204 / 255 . 45
= 54 . ( 4 . 5 )4 / (52)5 . 45
= 58 . 44 / 510 . 45
= 1 / 52 . 4
= 1 / 25 . 4
= 1 / 100
