Can someone prove that sqrt3(2+sqrt(5))-sqrt3(-2+sqrt(5))=1 ?

where sqrt3 means cube root and sqrt means square root or:where sqrt3 means cube root and sqrt means square rootor:sqrt3(2 + sqrt(5)) - sqrt3(-2 + sqr

where sqrt3 means cube root and sqrt means square root

or:where sqrt3 means cube root and sqrt means square root

or:sqrt3(2 + sqrt(5)) - sqrt3(-2 + sqrt(5)) = 1(2 + \u221a5)^(1/3) - (-2 + \u221a5)^(1/3) = 1Hold the Alt key and type 251 on the numeric keypad to get \u221a. Use Shift-6 for powers. 1.618 - 0.618 = 1http://www.alt-codes.net/
