Expert Answer:
The calculation becomes simpler if you factorise the numbers given under root sign and then you can make pairs of factors.
Example:
sqt (150*90*50*10)
= sqrt (3 * 5 * 10 * 3 * 3 * 10 * 5 * 10 * 10)
= sqrt (3 * 5 * 5 * 10 * 10 * 3 * 3 * 10 * 10)
= 5 * 10 * 3 * 10 sqrt (3)
= 1500 sqrt (3)
