Question

simplify: ( 4 + √3 )( 4 – √3 )​

Answer 1

Answer:

1st method :  

= ( 4 + √3 ) ( 4 - √3 )

Let ( a = 4 ) , and ( b = √3 )

= ( a + b ) ( a - b )

= ( a² - b² )

By substituting the values a and b.

= { (4)² - ( √3 )² }

= { 16 - 3 }

= 13.

2nd method :

= ( 4 + √3 ) ( 4 - √3 )

= 4 ( 4 - √3 ) + √3 ( 4 - √3 )

= 16 - 4√3 + 4√3 - ( √3 × √3 )

= 16 - 0 - 3

= 13.

The final answer is 13.

Answer 2

Step-by-step explanation:

$(4 + \sqrt{3} )(4 - \sqrt{3} ) \\ 4(4 - \sqrt{3} ) + \sqrt{3} (4 - \sqrt{3} )\\ 16 - 4 \sqrt{3} + 4 \sqrt{3} - \sqrt{9} \\ 16 - 3 \\ 13ans.$

i hope it will help you buddy..
