$100$ $100$

Explanation:

To evaluate an expression with $mixed operations$ $color(blue)"mixed operations"$ there is a particular order that must be followed.

Follow the order as set in the acronym PEMDAS [ Parenthesis(brackets), Exponents(powers), Multiplication, Division, Addition and Subtraction ]

$\Rightarrow 12 \times 2^{3} + 4$ $rArr12xx2^3+4$

$= 12 \times 8 + 4 \leftarrow Exponent$ $=12xx8+4larr" Exponent"$

$= 96 + 4 \leftarrow Multiplication$ $=96+4larr" Multiplication"$

$= 100 \leftarrow Addition$ $=100larr" Addition"$
