Let's break down and solve the given expression step by step:

The expression provided is:
\[ 2.5 \times 20 \times 3 \times 100 \]

We can simplify this by multiplying each pair of numbers step by step.

1. Multiply \( 2.5 \times 20 \):
\[ 2.5 \times 20 = 50 \]

2. Multiply the result by 3:
\[ 50 \times 3 = 150 \]

3. Finally, multiply the result by 100:
\[ 150 \times 100 = 15000 \]

So, the value of the expression \( 2.5 \times 20 \times 3 \times 100 \) is:
\[ 15000 \]
