if f(X)=x^1/3+ 1/3x what is the value of f(27)

The way it is written, exponents are done first, so it is x^1, then over 3, that is, x/3.

On the 2nd part, I would assume 1/3x is better written as x/3. It might be 1/(3x),

but rewriting it as x/3 makes it clear.

Given that, I assume this is f(x)=x^(1/3) + x/3.

It is known that 3*3*3=27, so 27^(1/3) = 3.

It is also known that 27/3 = 9.

Putting these two in gives 3 + 9 = 12, and that's the answer.
