To simplify the expression 6x2y2y23, we will follow the steps of combining like terms and performing multiplication.
1. **First, write the expression clearly:**
This can be expressed as:
6 * x2 * y2 * y2 * 3
2. **Now let’s group the coefficients and the variable parts:**
The coefficients are 6 and 3, which can be multiplied together:
6 * 3 = 18
3. **Next, we’ll simplify the variable parts:**
Here we have:
y2 * y2 = y{2+2} = y4
4. **Putting it all together:**
Thus, the expression simplifies to:
18x2y4
So, the correct simplification of the expression 6x2y2 * y2 * 3 is 18x2y4.
