Question

HELPPP PLEASEE SIMPIFY THIS EXPRESSION !!!!!

Answer 1

OPTION B IS THE CORRECT

Explanation:

`(√(2)+√(3))(√(5)-√(7))`

`√(2)(√(5)-√(7))+√(3)(√(5)-√(7))`

`√(2*5)-√(2*7)+√(5*3)-√(3*7)`

`√(10)+√(14)+√(15)-√(21)`

Answer 2

√10 + √15 -√14 - √21

Option B is the right option..

Solution,

`( √(2) + √(3) )( √(5) - √(7) ) \\`

Multiply each term in the first parantheses by each term in second paranthesis:

`√(2) * √(5) - √(2) * √(7) + √(3) * √(5) - √(3) * √(7) \\`

Calculate the product:

`√(10) - √(14) + √(15) - √(21) \\ √(10) + √(15) - √(14) - √(21)`

Hope this helps....

Good luck on your assignment..
