Question

simplify (5+√3)(5-√3)​

Answer 1

Answer:

22

Step-by-step explanation:

(5+√3)(5-√3)

∵(a+b)(a-b)=a²-b²

∴=(5)²-(√3)²

=25-3

=22 ANS

Answer 2

Answer:

Hence, the simplified form of (5 + √3)(5 - √3) is 22.

Step-by-step explanation:

Given:

(5 + √3)(5-√3)

To find:

Simplified form = ?

Solution:

We have,

(5 + √3)(5 - √3)

Now, this equation is in the form of (a+b)(a-b), were we have to put,

a = 5 and b = √3.

Using identity (a+b)(a-b) = a^2 - b^2, we get

=> (5 + √3)(5 - √3)

=> (5)^2 - (√3)^2

=> (5 × 5) - (√3 × 3)

=> (25 - 3)

=> 22.

Hence, the simplified form of (5 + √3)(5 - √3) is 22.
