|---|---|---|
| \(6 \times 10^{-3}\) | B2 | condone extra zeros which do not affect the value eg \(6.0 \times 10^{-3}\) B1 correct value not in standard form (allow value written as \(a \times 10^n\)) eg 0.006 or \(0.6 \times 10^{-2}\) or given calculation with 0.6 written as \(6 \times 10^{-1}\) eg \(6 \times 10^{-1} \div 100\) or value whose only non-zero digit is 6 correctly converted to standard form answer eg \(0.0006 = 6 \times 10^{-4}\) |
Additional guidance
| \(6 \times 10^{-1} \div 10^2\) | B1 |

|---|---|---|
| \(1.2 \times 10^8\) | B2 | condone extra zeros which do not affect the value eg \(1.20 \times 10^8\) B1 120 000 000 or 120 million or \(12 \times 10^7\) or \(120 \times 10^6\) or \(1.2 \times 10^a \times 10^b\) where \(a + b = 8\) or value whose only non-zero digits are 12 correctly converted to standard form answer eg \(12\,000\,000 = 1.2 \times 10^7\) |
