Answer 1

Answer:

Step-by-step explanation:

Given:

√23 + √528

To prove:

√23 + √528 = 2√3 + √11

Solution:

Consider,

2√3 + √11

Squaring,

( 2√3 + √11 )^2

This is of the algebraic expression ( a + b )^2

( a + b )^2 = a^2 + 2 ( a ) ( b ) + b^2

Substituing,

We get,

( 2√3 )^2 + 2 ( 2√3 ) ( √11 ) + ( √11 )^2

4 ( 3 ) + 4 ( √3 ) ( √11 ) + 11

23 + 4√33

Here,

4 = √16

Substituting,

We get,

23 + √16 * √33

23 + √528

Taking square root on both sides,

√23+√528

Hence, √23 + √528 = 2√3 + √11
