G.
2.67 × 108
H.
2.67 × 1016
J.
2.91 × 108
K.
2.91 × 100
To solve this expression, we need to follow the order of operations, which is parentheses, exponentiation, multiplication and division (from left to right), and addition and subtraction (from left to right).
First, we need to square the term (1.2 × 10^4) which is equal to (1.2 × 10^4)^2 = 1.44 × 10^8.
Now, we can substitute this value back into the original expression:
(4.11 × 10^8) - (1.44 × 10^8) = 2.67 × 10^8.
Therefore, the correct answer is G. 2.67 × 10^8.
