What is the following product?

-Dominant- [34]

Answer:

98 - 40√6

Step-by-step explanation:

We have to simplify the following product :

$(5\sqrt{2} - 4\sqrt{3})(5\sqrt{2} - 4\sqrt{3})$ .

Now, $(5\sqrt{2} - 4\sqrt{3})(5\sqrt{2} - 4\sqrt{3})$

= $(5\sqrt{2} - 4\sqrt{3})^{2}$

= $(5\sqrt{2})^{2} - 2 (5\sqrt{2}) (4\sqrt{3}) + (4\sqrt{3} )^{2}$

{Since we know the identity (a - b)² = a² - 2ab + b² }

= 50 - 40√6 + 48

= 98 - 40√6 (Answer)
