19 Write 500 as a product of powers of its prime factors. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| \(2^2 \times 5^3\) | M1 | for a complete method to find prime factors; could be shown on a complete factor tree with no more than one error or by division by prime factors with no more than one error |
| M1 | for complete factorisation, eg 2, 2, 5, 5, 5 | |
| A1 | for \(2^2 \times 5^3\) |
Additional guidance
Condone the inclusion of 1 for the method marks
Could be shown on a fully correct factor tree
