you need to find the factors of 1000, try to get one that’s a perfect square (e.g 49, 81, 36, 9) and you need to pick the biggest one. in this case it’s 100 because 100×10 = 1000 and 100 is perfect square of 10 (10×10 = 100)

So, it looks like this: 2√100×10

now, you take the square root of 100 (10) and multiply it by 2 so it looks like this: 2×10√10

which equals 20√10 <- that's the answer 2) it has a simple answer: √1,000,000 = 1000 because 1000x1000 = 1,000,000 hope it helped, good luck!

= 10 * 2 * sqrt(10)

= 20 * sqrt(5) * sqrt(2)

By inspection 2 * sqrt( 1000000 ) = 2000
