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.
