Simplify Exponents: First, let's simplify (−y2z4)2. We need to square both the y and z terms.(−y2)2=y2∗2=y4(z4)2=z4∗2=z8So, (−y2z4)2=y4z8
Multiply Terms: Now, multiply y4z8 by 3x2y3z. We combine like terms by adding the exponents for y and z. y4⋅y3=y4+3=y7z8⋅z=z8+1=z9 And multiply the coefficients: 1⋅3=3 So, y4z8⋅3x2y3z=3x2y7z9
Check for Errors: Now we check for any math errors in the previous steps.Everything looks correct, so we can conclude that the simplified form is 3x2y7z9.
