3sqrt(60) sqrt(4*15) sqrt(15) sqrt(15)(sqrt(5) sqrt(75)
------------- = ----------------- = ----------- or --------------------- = ---------------
3sqrt(20) sqrt(4*5) sqrt(5) sqrt(5)*sqrt(5) 5

sqrt(25)*sqrt(3) sqrt(3)
This reduces to ---------------------- = -------------
5

What exactly do you mean by " ^3 ?" That's not standard math'l notation.


Here's a different and better approach:

3 sqrt(60)
-------------- = sqrt(60/20) = sqrt(3) (answer)
3 sqrt(20)

Answer:


√(3) is the required quotient.

Explanation:

We have been given the expression:


(3√(60))/(3√(20))

Cancel the common term which is 3 we will be left with


(√(60))/(√(20))


√(60) can be written as after prime factorization is:


2√(15)

And
√(20) can be written as after prime factorization is:


2√(5)

Hence, the given expression would become after 2 gets cancel from numerator and denominator:


(√(3)\cdot √(5))/(√(5))

Quotient is the answer we get after dividing numerator by denominator and cancel common term which is
√(5)


√(3) is the required quotient.
