Question

What is the value of the expression 2+5\times4^2+5\times42+5×4 2 +5×4 ?

Answer 1

522

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
