Question

if a=3√5/2, b=√5/2, then find the value of (a+b)^2
$please find the value$

Answer 1

(a+b)² = (3√5/2 + √5/2)²

= (3√5+√5/2)²

= (4√5/2)²

= (2√5)²

= 4(5)

= 20

Hope it helps u :-)

Answer 2

HELLO.........FRIEND!!

THE ANSWER IS HERE,

$= > \: a = \frac{3 \sqrt{5} }{2}$

$= > \: b = \frac{ \sqrt{5} }{2}$

$= > \: ( {a + b)}^{2}$

$= > \: ( { \frac{3 \sqrt{5} }{2} + \frac{ \sqrt{5} }{2} })^{2}$

$= > \: \:( { \frac{4 \sqrt{5} }{2} )}^{2}$

$= > \: ({2 \sqrt{5}) }^{2}$

$= > \: 5 \times 4$

=> 20.
