It looks like you're trying to express a mathematical operation involving the number 2, and possibly an expression with \( b \). However, the formatting is a bit unclear.
If you meant to write \( 2 \cdot 2 \cdot 3 \cdot (4 + 3b) \), then you can simplify it as follows:
-
First, multiply the constants: \[ 2 \cdot 2 = 4 \] \[ 4 \cdot 3 = 12 \]
-
Now you have: \[ 12 \cdot (4 + 3b) \]
-
Distributing \( 12 \) gives: \[ 12 \cdot 4 + 12 \cdot 3b = 48 + 36b \]
So, \( 2 \cdot 2 \cdot 3 \cdot (4 + 3b) = 48 + 36b \).
If this is not what you intended, please provide more details or clarify the expression!
