Answer:
Step-by-step explanation:
I don't know exactly how simplified it will be, but you can get the square root smaller.
180: 2*2 * 3*3 *5
For every pair of prime factors you can take 1 of the pair outside the the square root and throw the other one away
sqrt(2*2*3*3*5) = 2 * 3 * sqrt(5) = 6*sqrt(5)
