Hope that you have understood how to represent root 5 on the number line. For reference go figure given below the first video in this lesion. Now, draw CB ⊥ AB and CB = 1 unit (as shown in first video). Now, join OC. The length of OC is root 6. At C, DC ⊥ AB. Join OD. Taking O as centre and OD as radius draw an arc that intersects the number line Q .
Here, OD = OQ = root 7.
Now, Q is the point on the number line that represents the number root 7.

What can you not do with square root?
When dealing with real numbers, you cannot take the square root of a negative number. The concept of the imaginary number was created to handle the square root of a negative number.That's almost like saying "when dealing with numbers bigger than 10, you cannot take the square root of 4. If what you are dealing with does not represent a number, then you cannot find its square root.
Square root of -1 is iota How?
Mathematicians decided that, since the square root of a negative number does not exist, they would use the first letter of "imaginary" to represent this "value".
