Here are the sums in standard form:

  1. 4.62×109+3.75×1094.62 \times 10^9 + 3.75 \times 10^9

  1. Since the powers of 10 are the same, add the coefficients.

    $$
(4.62 + 3.75) \times 10^9
$$

  2. Perform the addition.

    $$
8.37 \times 10^9
$$

  3. The result is already in standard form.

    $$
\boxed{8.37 \times 10^9}
$$

    2. 9.17×105+7.45×1069.17 \times 10^5 + 7.45 \times 10^6

  4. Convert one of the numbers so that both have the same power of 10.

    It's usually easier to convert the smaller power to the larger power. 9.17×105=0.917×106 9.17 \times 10^5 = 0.917 \times 10^6

  5. Add the numbers with the common power of 10.

    $$
0.917 \times 10^6 + 7.45 \times 10^6 = (0.917 + 7.45) \times 10^6
$$

  6. Perform the addition.

    $$
8.367 \times 10^6
$$

  7. The result is already in standard form.

    $$
\boxed{8.367 \times 10^6}
$$
