The product of 3xy2z and 4x is:
⇒ (3xy2z) (4x)
⇒ 3.x.y2.z.4.x
⇒ 12x2y2z
The product of 3xy2z and 4x is:a)12xyzb)12xy2c)12x2y2zd)12x2yzCorrect ...
Understanding the Problem
To find the product of the expressions 3xy2z and 4x, we start by identifying the components of both expressions.
Components of the Expressions
- The first expression is 3xy2z:
- 3 is the coefficient.
- x, y2 (which means y squared), and z are the variables.
- The second expression is 4x:
- 4 is the coefficient.
- x is the variable.
Calculating the Product
Now, we multiply the coefficients and the variables separately:
1. Multiply the coefficients:
- 3 (from 3xy2z) * 4 (from 4x) = 12.
2. Multiply the variables:
- From 3xy2z, the variables are x, y2, and z.
- From 4x, the variable is x.
- Combining these:
- x (from 3xy2z) + x (from 4x) = x^2 (since we add exponents of the same base).
- y remains as y2 (since we are not multiplying y2 with anything).
- z remains as z.
Final Expression
Putting it all together, we have:
- Coefficient: 12
- Variables: x^2, y^2, z
Thus, the final product is:
12x^2y^2z
Conclusion
Therefore, the correct answer is option 'C' - 12x2y2z.
