Question

Resolva e simplifique:

(1 / (√5 - √2) ) + ( 51/2 )

Answer 1

(1 / (√5 - √2) ) + ( 51/2 ) = x

MMC = 2(√5 - √2)

2 + 51(√5 - √2) = x (2(√5 - √2))
x = (2+51(√5 - √2)) / (2(√5 - √2))
x =  (2+51(√5 - √2)) / (2(√5 - √2))
√5 =  2,23
√2 =  1,41

x = (2+51(2,23 - 1,41)) / (2(2,23 - 1,41))
x = (2+51(0,82)) / 2(0,82)
x = (2+41,82)/ 16,4
x = 39,82/16,4
x ≈ 2,40
