Answer 2

Concept:

Simplifying an expression means to reduce the expression in its lowest form. This can be done by using the various operations of mathematics.

Given:

We are given an expression:

28 / (√28-√7)

Find:

We need to simplify the expression 28 / (√28-√7).

Solution:

We have:

28 / (√28-√7)

We can also write √28 as:

28 = 7 × 4

√28 = √7 × √4

√28 = 2√7

So, the expression becomes:

= 28 / (2√7 - √7)

= 28 / √7

= √28 × √28 / √7

= 4 √7

Therefore, after simplifying the expression 28 / (√28-√7), we get the value as 4 √7.
