Respuesta :

The simplified form of the function will be (√10 - √10 + √15 - √21 ).

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The expression will be calculated as:-

(√2  + √3 ) ( √5 - √7 ) = √2 (√5 + √7 ) + √3 ( √5 - √7 )

                                    = √2√5 + √2√7 + √3√5 - √3√7

                                    = √10 + √14 + √15 - √21

Therefore simplified form of the function will be (√10 - √10 + √15 - √21 ).
