To add \(7.3 \times 10^7\) and \(1.8 \times 10^7\), you can combine them since they have the same exponent.
\[ 7.3 \times 10^7 + 1.8 \times 10^7 = (7.3 + 1.8) \times 10^7 = 9.1 \times 10^7 \]
Therefore, the correct sum is:
O 9.1 * 10 ^ 7.
Add 7.3 * 10 ^ 7 + 1.8 * 10 ^ 7 Which is the correct sum? (1 point)
O 8.1 * 10 ^ 7
O 9.1 * 10 ^ 7
Ο 9.1 + 10 ^ 7
O 9.1 * 10 ^ 14
