Answer 1

Answer:

93 - 24√15

Step-by-step explanation:

We have to do nothing but just use the identity

(a + b)² = a² + b² + 2ab

Solution:

${(4 \sqrt{3} - 3 \sqrt{5}) }^{2} \\ \\ {(4 \sqrt{3} ) }^{2} - 2.4 \sqrt{3} .3 \sqrt{5} + {(3 \sqrt{5}) }^{2} \\ \\ 16.3 - 24 \sqrt{3.5} + 9.5 \\ \\ 48 + 45 - 24 \sqrt{15} \\ \\ 93 - 24 \sqrt{15}$
