3.2 x 104 + 1.95 x 106

The sum of 3.2 x 104 and 1.95 x 106 is 2.2819 x 106.

To solve this problem, we need to add the numbers 3.2 x 10^4 and 1.95 x 10^6.

To add these numbers, we need to make sure they have the same exponent. In this case, the exponent in 3.2 x 10^4 is 4, and the exponent in 1.95 x 10^6 is 6. We can rewrite 3.2 x 10^4 as 0.032 x 10^6.

Now that both numbers have the same exponent, we can add them.

0.032 x 10^6 + 1.95 x 10^6 = (0.032 + 1.95) x 10^6

Adding the decimal numbers: 0.032 + 1.95 = 1.982

Therefore, the sum is 1.982 x 10^6.

To add these numbers together, you have to make sure their exponents (powers of 10) are the same. In this case, you need to convert 3.2 x 10^4 to the same exponent as 1.95 x 10^6.

Step 1: Convert 3.2 x 10^4 to scientific notation with the same exponent as 1.95 x 10^6.
3.2 x 10^4 = 0.32 x 10^5

Step 2: Now that both numbers have the same exponent, you can add them together:
0.32 x 10^5 + 1.95 x 10^6

Step 3: Add the numbers without the exponents:
0.32 + 1.95 = 2.27

Step 4: Keep the larger exponent (10^6):
2.27 x 10^6

Therefore, 3.2 x 10^4 + 1.95 x 10^6 = 2.27 x 10^6.
