(b) Simplify \((m^2)^{-3}\) (1)
| Answer | Mark | Mark scheme |
|---|---|---|
| \(14x^5y^6\) | B2 | cao |
| (B1 | for correct simplification of two terms \(ax^5y^6\) or \(14x^by^6\) or \(14x^5y^c\) where \(a \neq 14\), \(b \neq 5\), \(c \neq 6\)) |
Additional guidance
Where \(a\), \(x^b\), \(y^c\) can be made up of two products
Condone inclusion of multiplication signs for B1
| Answer | Mark | Mark scheme |
|---|---|---|
| \(m^{-6}\) | B1 | for \(m^{-6}\) or \(\dfrac{1}{m^6}\) |
