Answer 2

Answer:

When we simplify the equation then the answer is $30-11\sqrt{10}$.

Step-by-step explanation:

According to the question , we need to simplify a equation which are given in the question, it is $( 3\sqrt{5}-5\sqrt{2} )(4\sqrt{5}+3\sqrt{2} )$. We need to simplify the equation. It is a very easy equation , we need to multiply the $2nd$ part of the equation with the first number of the first part and then multiply the $2nd$part with the $2nd$ number of the $1st$ part of the equation.

$( 3\sqrt{5}-5\sqrt{2} )(4\sqrt{5}+3\sqrt{2} )\\\\= (12*5)+9\sqrt{10}-20\sqrt{10}-(15*2)\\ \\= 60-30-11\sqrt{10}\\ \\= 30-11\sqrt{10}$
