Answer 1

open it by using Identity

like

4✓3²+3√5²-2×4√3×3√5

so

48+45-92.95

93-82.95

it's 0.05 Answer

Answer 2

Answer:

93-24(√15)

Step-by-step explanation:

( 4√3 - 3√5 )²

= (4√3)² - 2(4√3)(3√5) + (3√5)²

= (16×3) - 24(√3×√5) + (9×5)

= 48 + 45 -24(√15)

= 93 - 24(√15)

= (31×3) - (3×8×√15)

= (31×3) - (3×8×√15)= 3(31 - 8√15)
