(a) Simplify \(m^{10} \div m^3\) (1)
\(k^n \times k^4 = k^{12}\)
(b) Write down the value of \(n\) (1)
(c) Simplify \((3x^6y^8)^2\) (2)

| (4 marks) |
Notes
B2: B1 for a product in the form \(ax^py^q\) where 2 from \(a\), \(p\) or \(q\) are correct eg \(3x^{12}y^{16}\)
(Allow \(9x^{12}\) or \(9y^{16}\) or \(x^{12}y^{16}\) so as long as not added to any other terms)
