The expression is:

$4^2 + 2 \times 10$

We follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

1. Calculate the exponent:
   $4^2 = 16$

2. Perform the multiplication:
   $2 \times 10 = 20$

3. Add the results:
   $16 + 20 = 36$

So, the value of the expression is $36$.
