36930
Step-by-step explanation:
The given numbers: 3.65 x 104 and 4.3 x 102
I will be assuming the numbers are: 3.65 x 10⁴ and 4.3 x 10²
we expand each of the numbers in standard form before we can sum them together.
3.65 x 10⁴ = 36500
4.3 x 10² = 430
3.65 x 10⁴ + 4.3 x 10² = 36500 + 430
3.65 x 10⁴ + 4.3 x 10² = 36930
