work.

Answer 1

Let's choose 3.2 x 10^4 and 1.95 x 10^6 to add together.

To add these numbers, we must first make sure that the powers of 10 are equal. In this case, we can convert 3.2 x 10^4 to 3.2 x 10^6.

Now we can add the numbers:

3.2 x 10^6 + 1.95 x 10^6

= (3.2 + 1.95) x 10^6

= 5.15 x 10^6

So, the sum of 3.2 x 10^4 and 1.95 x 10^6 is 5.15 x 10^6.
