√15 = 3.872...
√20 = 4.472...
3√15 = 3(3.872.....) = 11.618.....
4√20 = 4(4.472.....) = 17.8885....
We can clearly see that 4√20 is greater.
So 4√20 is greater than 3√15.

Concept:
If the number under square root is greater then the value of square root will be greater.
Square root of a number suggests that square of which number is equal to that number under root.
Given:
Given square roots are 3√15 and 4√20
Find:
We have to find which one of the above is greater.
Solution:
If we calculate and make all the number under square root for both the given number we have
3√15 = √9*√15 = √(9*15) = √135
4√20 = √16*√20 = √(16*20) = √320
Since 320 > 135 so it follows √320 > √135
That is 4√20 > 3√15
Hence 4√20 is the greater among the given numbers.
