use scientififc notation 1.4 х 10^3 + 3.6 x 10^3

Answer 1

To add numbers written in scientific notation, you must first make sure both numbers have the same exponent. In this case, you can rewrite the numbers as:

1.4 x 10^3 + 3.6 x 10^3

Since both numbers have the same exponent (10^3), you can add the coefficients:

1.4 + 3.6 = 5

So, the sum of 1.4 x 10^3 and 3.6 x 10^3 is 5 x 10^3.
