Answer 2

Ответ: 621/2000 или 0.3105

Answer 3

To calculate the sum of the given numbers in scientific notation, you need to add the coefficients while keeping the exponent the same.

Let's add the numbers:

3 * 10^(-1) + 1 * 10^(-2) + 5 * 10^(-4)

First, let's bring all the numbers to the same exponent:

3 * 10^(-1) = 0.3 * 10^0 1 * 10^(-2) = 0.01 * 10^0 5 * 10^(-4) = 0.0005 * 10^0

Now we can add the coefficients:

0.3 + 0.01 + 0.0005 = 0.3105

The common exponent is 10^0, so the final sum is:

0.3105 * 10^0

In standard notation, this is equal to 0.3105.
