2.77 x 103
+ 1.04 x 104
= 2.77 x 10^3 + 1.04 x 10^4
= 2770 + 10400
= 13170
To add these two numbers, you need to align the decimal points, if any, and then perform the addition:
2.77 x 10^3
+ 1.04 x 10^4
We can't simply add the coefficients (2.77 and 1.04) because they have different powers of 10. To align the powers of 10, we can rewrite the first number as:
2.77 x 10^3 = 0.277 x 10^4
Now we can add:
0.277 x 10^4
+ 1.04 x 10^4

1.317 x 10^4
So, the sum of 2.77 x 10^3 and 1.04 x 10^4 is 1.317 x 10^4.
