Can you help me with this indices question

Simplify ((³√√a³+b²)+b)((³√√a³+b²)-b) . FYI if you can't understand the question: the cube root is for a^3+b^2 + or - b. only the square root is for a^3+b^2.

Hi,

((³√√a³+b²)+b)((³√√a³+b²)-b)

Multiply these together under the cube root as the difference of perfect squares.

((³√√a³+b²)+b)((³√√a³+b²)-b) =

³√a³+b² - b² = ³√a³ = a <==ANSWER

I hope that helps!! :-)
