Scientific Notation question...

It says put it in scientific notation and here is the question.

3100.0 x 10^2

But it's already in scientific notation... and I have no clue what to do... I've never done a question in scientific notation before... can someone please help me?

I suppose you could change it to 31*10^4; it's all I can think to do here.

3.1 * 10^5

what is the answer Evaluate the expression using two different methods. Write your answer in scientific notation.

(2.74×107)+(5.6×107)

Of course! I can help you understand how to convert the given number into scientific notation.

Scientific notation is a way of writing numbers as a product of a number between 1 and 10 (known as the coefficient) multiplied by a power of 10 (known as the exponent). The goal is to express a number in a more concise form, especially when it is very large or very small.

Let's break down the given number, 3100.0 x 10^2, into its components:

Coefficient: 3100.0 (the number before the "x")
Exponent: 10^2 (the power of 10 after the "x")

To convert this number into scientific notation, we need to move the decimal point in the coefficient so that there is only one non-zero digit to the left of the decimal point. The number of places moved will determine the exponent.

In this case, since the coefficient is already in decimal form, we just need to move the decimal point 2 places to the left. This will result in a coefficient of 31.00.

Now that the decimal point has been moved to the left, the exponent remains the same, 10^2.

Putting it all together, the number 3100.0 x 10^2 can be expressed in scientific notation as 31.00 x 10^2.

It's worth noting that in scientific notation, trailing zeros after the decimal point are significant and indicate the level of accuracy of the measurement.

I hope this explanation helps you understand how to convert numbers into scientific notation. If you have any further questions, feel free to ask!
