Svar:
#g (3) = 6 #
Forklaring:
Bare erstat 3 i hvor der er en #x#
#g (3) = rod (3) (3 ^ 2-1) + 2sqrt (3 + 1) #
#g (3) = rod (3) 8 + 2sqrt4 #
#g (3) = 2 + 2sqrt4 #
#g (3) = 2 + 2xx2 #
#g (3) = 2 + 4 #
#g (3) = 6 #
Svar:
#g (3) = 6 #
Forklaring:
Prop #3# i for #x#
#g (3) = root3 (3 ^ 2-1) + 2sqrt (3 + 1) #
Forenkle
#g (3) = root3 (9-1) + 2sqrt (4) #
#g (3) = root3 (8) + 2sqrt (4) #
#g (3) = 2 + 2 (2) #
#g (3) = 2 + 4 #
#g (3) = 6 #
