Question

simplify (4√3-3√5)^2

Answer 1

hiii!!!

here's ur answer...

given :- (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..!!

GIVEN THAT :$(4 \sqrt{3} - 3 \sqrt{5} ) {}^{2} \\ \\ using \: identity \: (a - b) {}^{2} = {a}^{2} + {b}^{2} - 2ab \\ \\ = > (4 \sqrt{3} ) {}^{2} +( 3 \sqrt{5} ) {}^{2} - 2(4 \sqrt{3} )(3 \sqrt{5} ) \\ \\ = > 48 + 45 - 24 \sqrt{15} \\ \\ = > 93 - 24 \sqrt{15} ........$
