Question

What is the following product?

Answer 1

Answer:

98-40 sqrt 60 so it would be D on edge

Step-by-step explanation:

I got it right on edge

Answer 2

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)
