Foundation November 2024 Paper 2 Q27
27 \(1.25 \times 10^{-12} = k \times (4 \times 10^{-20})\)
Work out the value of \(k\).
Give your answer in standard form. (2)
| Answer | Mark | Mark scheme |
|---|---|---|
| \(3.125 \times 10^7\) | M1 | for \((k =)\ (1.25 \times 10^{-12}) \div (4 \times 10^{-20})\) or for the digits 3125 |
| A1 | cao |
Additional guidance
Condone missing brackets on division
\(3.1 \times 10^7\) or \(3.12 \times 10^7\) or \(3.13 \times 10^7\) will score M1A0
