find the sum of 1.381 × 10^9 and 3.23 × 10^8. the sum is 0.49 1.704 4.611 × 10^9. 10^15. 10^17.

Explanation:

Step1: Rewrite numbers with same exponent

Rewrite $3.23\times 10^{8}$ as $0.323\times 10^{9}$.

Step2: Add the coefficients

$1.381 + 0.323=1.704$.

Step3: Keep the common exponent

The sum is $1.704\times 10^{9}$.

Answer:

$1.704\times 10^{9}$
