Step-by-step explanation:
step 1: factor both the numerator and the denominator
step 2: write as on fraction
step 3: simplified the rational expression
step 4: multiply any remaining factors in numerator and or denominator
step 5: factor both the numerator and the denominator
step 6: write as on fraction
The quotient is twice 405.5. Whenever dividing by .5 you multiply by 2 instead

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 ).
