I think each of those numbers and letter in the equation are different parts, so follow the order of operations. First is the cube root of t and next you multiply, then add. The order of operations can be remembered using PEMDAS (things in Parentheses are first, then Exponents, Multiplication/Division and the last are Addition/Subtraction)

Hint: using the equation as follows, follow instructions of @Hally85 to get the correct answer:
$S=9t^{1/3}+7.1$
