Answer:

c) ( $(6-\sqrt{12} )(6+\sqrt{12} ) = 24$

d) ( $(3+\sqrt{8} )(3-\sqrt{8} ) = 1$

Step-by-step explanation:

Step(i):-

Given that the binomial expression

( $(6-\sqrt{12} )(6+\sqrt{12} )$

Multiply

( 36 + 6√12 -6√12 -(√12)²)

= ( 36 -12)

= 24

c) ( $(6-\sqrt{12} )(6+\sqrt{12} ) = 24$

Step(ii):-

Given that the binomial expression

( $(3+\sqrt{8} )(3-\sqrt{8} )$

Multiply

= 9 - 3√8 + 3√8 -(√8)²

= 9 - 8

= 1

d) ( $(3+\sqrt{8} )(3-\sqrt{8} ) = 1$
