I need help on number 4

Answer:
√1,000,000 is the square root of 1,000 so √1,000,000=1,000
√36 is the square root of 6. So
√36=6
To check our work: 1,000•1,000 equals what? 1,000,000! So this is true.
For √36: what's 6•6? 36!! So this is also true.
We can also see the square roots for the other numbers are:
√3=1.73
√6=2.44
√100=10
√1000=31.62
So we match the right ones together which is √1,000,000=1,000 and √36=6
Hope this helps! If so please mark brainliest and rate/heart to help my account if it did!!
