Re: Numerical expression

Adding the necessary parentheses:
((9 (3)^(1/2) + 4 (23)^(1/2))^(1/3) + (9 (3)^(1/2) + 4 (23)^(1/2))^(1/
3))/(3)^(1/2)
this comes out to
(2*(9*Sqrt[3] + 4*Sqrt[23])^(1/3))/Sqrt[3]
(2*(9*Sqrt[3] + 4*Sqrt[23])^(1/3))/Sqrt[3]//N
gives
3.76887
So it's not 1.
Cheers,

How could I handle in Mathematica this expression?
( ( 9(3)^1/2+4(23)^1/2)^1/3 + (9(3)^1/2+4(23)^1/2)^1/3 ) / (3)^1/2)
With a lot of trouble I have found out that is equal 1,
but how to get it with Mathematica?
Thanks very much.
