To find the greatest common factor (GCF) of the expression \(4x^2y^5 + 10x^3y^4\), we need to analyze the coefficients and the variables.
-
Coefficients:
- The coefficients are 4 and 10.
- The GCF of 4 and 10 is 2.
-
Variable parts:
- For \(x^2\) and \(x^3\), the lowest power is \(x^2\).
- For \(y^5\) and \(y^4\), the lowest power is \(y^4\).
Putting it all together, the GCF is: \[ 2x^2y^4 \]
So, the greatest common factor of the expression \(4x^2y^5 + 10x^3y^4\) is \(2x^2y^4\).
The correct response is: 2 x squared y to the 4th power.
