Question

can imaginary numbers be represented on number line if yes, how
can you represent square root of -4 on number line



​

Answer 1

yes imaginary numbers can be represented on number line..

Draw a line segment AB=-4 units and extend it to C such that BC=1 unit.

Find the mid point O of AC.With O as centre and OA as radius , draw a semi circle at D.

Then , BD =√-4 units.

With B as centre and BD as radius , draw an arc , meeting AC produced at E.

Then, BE=BO=√-4 units .

plzz lemme know if i helped.

Answer 2

Answer:

Hello There,

You can represent imaginary numbers on number line.

Step-by-step explanation:

Actually, yes. But a one-dimensional number line will not sufficient. The pure imaginary part of the complex number needs to be represented on a second number line. In other words, we need a two-dimensional picture to represent complex numbers. Here is a picture of the number 2+3i, represented by a point.

This is your answer.
