First, compute the exponents, then the multiplication, and lastly the addition:

$= 2 + 2 {(2)}^{2} (5) + 8$ $color(white)=2+2(2)^2(5)+8$

$= 2 + 2 \cdot 2^{2} \cdot 5 + 8$ $=2+2*2^2*5+8$

$= 2 + 2 \cdot 4 \cdot 5 + 8$ $=2+2*4*5+8$

$= 2 + 8 \cdot 5 + 8$ $=2+8*5+8$

$= 2 + 40 + 8$ $=2+40+8$

$= 42 + 8$ $=42+8$

$= 50$ $=50$
