  1. The expression which represents the correctly rewritten form of the given expression; 20x⁴y³ – 30x³y⁴ is; 5x³y³ ( 4x – 6y ).

    Which expression correctly represents the rewritten form of the expression 20x⁴y³ – 30x³y⁴?

    It follows from the task content that the expression which correctly represents the rewritten form of the given expression be determined.
    On this note, since the given expression is;
    20x⁴y³ – 30x³y⁴
    The greatest common factor of both terms in the expression is; 10x³y³ .
    On this note, the expression can be factorised completely as follows;
    10x³y³ ( 2x – 3y )
    However, the expression which is equivalent to the expression above among the answer choices is;
    5x³y³ ( 4x – 6y )
