# (2) "" 2 ^ (1/4) (sqrt (2) + sqrt (3)) #

Forklaring:

# x ^ 2 = sqrt (48) + sqrt (50) #

# => x ^ 2 = 4 sqrt (3) + 5 sqrt (2) #

# => x ^ 2 = (4 sqrt (6) + 10) / sqrt (2) #

# => x ^ 2 = (2 + sqrt (6)) ^ 2 / sqrt (2) #

# => x = (2 + sqrt (6)) / 2 ^ (1/4) #

# => x = 2 ^ (1/4) (sqrt (2) + sqrt (3)) #
