Answer:
522
Step-by-step explanation:
I solve this question using PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction).
2 + 5 x 4² + 5 x 42 + 5 x 42 + 5 x 4
= 2 + 5 x 16 + 5 x 42 + 5 x 42 + 5 x 4
= 2 + (5 x 16) + (5 x 42) + (5 x 42) + (5 x 4)
= 2 + 80 + 210 + 210 + 20
= 522
