Question

Simply the following (√3+√7) (√3-√7)

Answer 1

Hii friend,


=> (✓3+✓7)(✓3-✓7)

we know that (a+b) × (a-b) = a²-b² , where a = ✓3 and b = ✓7


Therefore,


=> (✓3)² - (✓7)²

=> 3 - 7

=> -4

HOPE IT WILL HELP YOU.... :-)

Answer 2

$( \sqrt{3} + \sqrt{7} ) ( \sqrt{3} - \sqrt{7} ) \\ { \sqrt{3 } }^{2} - { \sqrt{7 } }^{2} \\ 3 - 7 \\ - 4$
