UpStudy AI · Accepted Answer

To compute $$ \left(7.3 \times 10^{5}\right) + \left(4 \times 10^{5}\right) $$ and express the result in standard index (scientific) form, follow these steps:

1. **Add the Coefficients:**
   $$
   7.3 + 4 = 11.3
   $$
   
2. **Combine with the Common Exponent:**
   $$
   11.3 \times 10^{5}
   $$

3. **Adjust to Proper Scientific Notation:**
   In standard scientific notation, the coefficient should be between 1 and 10. To adjust:
   $$
   11.3 \times 10^{5} = 1.13 \times 10^{6}
   $$
   
   (Here, $$11.3 \times 10^{5}$$ is rewritten by moving the decimal one place to the left, which increases the exponent by 1.)

**Final Answer:**
$$
1.13 \times 10^{6}
$$
The sum is $$1.13 \times 10^{6}$$.
