Answer 2

To perform the subtraction of these two numbers written in scientific notation, you need to first make sure that they have the same exponent. In this case, both numbers have exponents of 3.

So, the subtraction would be:

(1.6 * 10^3) - (1.4 * 10^3)

Now, you can subtract the decimal parts:

1.6 - 1.4 = 0.2

Keep the exponent as 10^3:

0.2 * 10^3

Now, you have your result in scientific notation:

0.2 * 10^3 = 2 * 10^2

So, the result is 2 * 10^2.
