(a) Simplify \((3a^2b)^4\) (2)

(b) Simplify \((9c^8)^{\frac{1}{2}}\) (2)

Mark scheme (a)

Scheme	Marks
\(81a^8b^4\)	B2
	(2)

Notes

B2: B1 for 81 B1 for \(a^8b^4\)

Apart from Questions 9, 13, 18, 20 and 21 (where the mark scheme states otherwise) the correct answer, unless clearly obtained by an incorrect method, should be taken to imply a correct method.
