Please my friends tell this answer step by step​

Answer 1

Answer ;  (4√3 - 3√5)²

we will use second identity of algebraic expression here.. that is ( a - b )² = a² - 2ab + b²

here a = 4√3 and b = 3√5

= (4√3)² - 2 (4√3) (3√5) + (3√5)²

= 16(3) - 24√15 + 9(5)

= 48 - 24√15 + 45

= 93 - 24√15

hope this helps..!!

Pls mark me as barinliest !!

Answer 2

Answer:

77 - 24√10

Step-by-step explanation:

(4√2 - 3√5)^2

= (4√2)^2 - (2 × 4√2 × 3√5) + (3√5)^2

= 16 × 2 - 24√10 + 9 × 5

= 32 - 24√10 + 45

= 77 - 24√10
