Let's clarify and simplify the given expression step by step using the properties of integer exponents.
The expression you've described can be interpreted as:
\[ (2XY^3)^{4} \cdot (X^2Y)^{3} \]
Let's break this down:
-
Expand \( (2XY^3)^{4} \):
- \( 2^{4} \)
- \( X^{4} \)
- \( (Y^3)^{4} = Y^{12} \)
Therefore, we have: \[ (2XY^3)^{4} = 16 X^{4} Y^{12} \]
-
Expand \( (X^2Y)^{3} \):
- \( (X^2)^{3} = X^{6} \)
- \( (Y)^{3} = Y^{3} \)
Therefore, we have: \[ (X^2Y)^{3} = X^{6} Y^{3} \]
-
Combine the two parts: Now we need to multiply the results: \[ (16 X^{4} Y^{12}) \cdot (X^{6} Y^{3}) \]
The multiplication of the coefficients and the exponents gives:
- Coefficients: \( 16 \)
- For \( X \): \( X^{4} \cdot X^{6} = X^{4+6} = X^{10} \)
- For \( Y \): \( Y^{12} \cdot Y^{3} = Y^{12+3} = Y^{15} \)
Putting it all together, we have: \[ 16 X^{10} Y^{15} \]
Thus, the simplified expression is:
\[ 16 X^{10} Y^{15} \]
From the options provided, the correct choice is:
16 X small 10 on top small 15 on top.
