Answer:
100
Step-by-step explanation:
Prime factors of 2000
= (2x2)x(2x2)x(5x5)x5
5 has no pair
therefore, 5 is the least number that must be multiplied by 2000 to get a perfect square.
2000x5= (2x2)x(2x2)x(5x5)x(5x5)
= 10,000
square root of 10,000 = (2x2x5x5)
= 100
This is the right answer......
Hope it helps u :)
