Question

(√5+3)²=a+b√5 answer fast​

Answer 1

Answer:

A=14, B= 6

Step-by-step explanation:

$(\sqrt{5} +3)^{2} = A+B\sqrt{5}$

5+9+6$\sqrt{5}$=A+B$\sqrt{5}$

A=14

AND

B= 6

Answer 2

Step-by-step explanation:

Given (3+√5)/(3-√5) = a+b√5

(3+√5)(3+√5)/(3-√5)(3+√5) = a+b√5

(9+6√5+5)/(9–5) = a+b√5

(14+6√5)/4 = a+b√5

7/2 + 3√5/2 = a+b√5

Hence a= 7/2 and b= 3/2.
