To solve the problem of multiplying 0.1 by 2.3 fifteen times in detail, we can break it down step-by-step.

Step 1: Understand the Problem

You are asked to:

• Multiply $0.1 \times 2.3$
• Repeat the multiplication 15 times.

This can be interpreted as multiplying $0.1 \times 2.3$ and then raising that result to the 15th power.

Step 2: First Multiplication

Let's calculate the initial multiplication: $0.1 \times 2.3 = 0.23$

Step 3: Repeated Multiplication (Power)

Now, you want to repeat this multiplication 15 times, which is equivalent to raising $0.23$ to the power of 15.

$0.23^{15}$

Step 4: Calculation

Let's calculate $0.23^{15}$.

$0.23^{15} = 2.55829121875 \times 10^{-9}$

This is a very small number, approximately $0.000000002558$.

Final Answer:

$0.1 \times 2.3 \text{ repeated 15 times} = 2.558 \times 10^{-9}$

This result shows that repeating this multiplication results in a very small value.
