CORRECT EXPLANATION WILL BE MARK AS BRAINLIEST.

Let us assume that:

We can also write it as:

Squaring both sides, we get:

By splitting the middle term:

Therefore:

But x cannot be negative.

Therefore, the value of the expression is 3.

Given:

We can also write it as:

This pattern will continue.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
