Easy -1.2 This is a straightforward algebraic manipulation question requiring only routine application of index laws (power of a product, multiplication of powers, division of powers). It involves multiple steps but no problem-solving or conceptual insight—purely mechanical simplification that any competent C1 student should handle with basic recall.
Question 7:
7 | 4x4
4x4y-3 or as final answer
y3 | 3
[3] | B1 each ‘term’;
or M1 for numerator = 64x15y3 and M1 for
denominator = 16x11y6 | B0 if obtained fortuitously
mark B scheme or M scheme to
advantage of candidate, but not a
mixture of both schemes
