Question

\(\dfrac{5^5.20^4}{25^4.4^5}\)

Answer 1

\(=\dfrac{5^5\cdot5^4\cdot4^4}{4^5\cdot5^8}=\dfrac{5}{4}\)

Answer 2

\(\dfrac{5^5.\left(5.4\right)^4}{\left(5.5\right)^4.4^5}=\dfrac{5^9.4^4}{5^8.4^5}=\dfrac{5}{4}\)

Answer 3

= 5/4

Answer 4

`= (5^5 . 5^4 . 2^8)/(5^8 . 2^10)`.

`= 5/2^2`

`= 5/4`
