Answer 1

u sure

Answer 2

positive ?

Answer 3

To express the number \(0.000000003\) in the form of \(a \times 10^n\) where \(1 < a < 10\):

1. First, rewrite \(0.000000003\) as \(3\) multiplied by \(10^{-9}\).

\[
0.000000003 = 3 \times 10^{-9}
\]

Thus, the correct expression is:

**3 × 10⁻⁹**

So the answer is \(3 \times 10^{-9}\).

Answer 4

Yes, I'm sure. Let's break it down to make it clear:

1. The number \(0.000000003\) can be rewritten as:
\[
3 \times 10^{-9}
\]

2. In scientific notation, we express numbers in the form \(a \times 10^n\), where \(1 < a < 10\). In this case, \(a = 3\) and \(n = -9\).

3. Therefore, \(0.000000003\) is correctly represented as:
\[
3 \times 10^{-9}
\]

If this matches your original question about converting the number into scientific notation, then that is indeed the correct representation. If you have any further questions or need clarification, feel free to ask!

Answer 5

I apologize for the confusion. To clarify, the number \(0.000000003\) is indeed a very small positive number, and when expressed in scientific notation, it is correctly written as:

\[
3 \times 10^{-9}
\]

This indicates that it is a positive number, as the exponent is negative, meaning the decimal point has been moved to the left.

If you have a different number in mind or need clarification on something else, please let me know!
