Mong các bạn giúp. Mk sẽ tick. 

Answer 1

\(\left(5^{65}:5^{60}\right):\left(5^1.5^3\right)=\left(5^{65-60}\right):\left(5^{1+3}\right)=5^5:5^4=5^{5-4}=5^1=5\)

Answer 2

=> \(5^5\): \(5^4\)= \(5^{5-4}=5^1=5\)

Answer 3

\(\left(5^{65}:5^{60}\right):\left(5^1.5^3\right)\)

\(=5^{65-60}:5^{1+3}\)

\(=5^5:5^4\)

\(=5^{5-4}\)

\(=5^1\)

\(=5\)
