What is an expression?</h3>
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 ).

Answer:
no solutions
Step-by-step explanation:
5 -2 sqrt(x) = 11
Subtract 5 from each side
5- 5 -2 sqrt(x) = 11-5
-2 sqrt (x) = 6
Divide each side by -2
-2/-2 sqrt(x) = 6/-2
sqrt(x) = -3
The sqrt(x) must be 0 or positive
