Question

What is the following product? (√14-√3)(√12+√7)

Answer 1

Answer:

2√42 + 7√2 - √21 - 6

Step-by-step explanation:

(√14-√3)(√12+√7)

First let us expand the expression by doing the following:

√14(√12+√7) -√3(√12+√7)

√168 + √98 - √36 - √21

√(4x42) + √(49x2) - 6 - √21

2√42 + 7√2 - √21 - 6

Answer 2

Answer:

12.28

Step-by-step explanation:

$\sqrt{14}-\sqrt{3} )(\sqrt{12}+\sqrt{7})$

Multiplying $\sqrt{14} and\sqrt{3}$ individually to the values inside the brackets to find the product of the equation.

$\sqrt{14}\sqrt{12}+\sqrt{14}\sqrt{7}-\sqrt{3}\sqrt{12} -\sqrt{3} \sqrt{7}$

$\sqrt{168} +\sqrt{98} -\sqrt{36}- \sqrt{21}\\2\sqrt{42}+7\sqrt{2}-6-\sqrt{21}\\ 12.96 +9.90 -6 -4.58\\12.28$

                 

The product of the above values is 12.28
