| \(1.5 \times 1.5\) or \(\left(\dfrac{3}{2}\right)^2\) | M1 | oe oe improper fraction squared |
| 2.25 or \(\dfrac{9}{4}\) or \(2\dfrac{1}{4}\) | A1 | oe decimal, improper fraction or mixed number SC1 answer digits 225 |
Additional guidance

| Do not allow further work, but condone adjusting place value eg \(1.5 \times 1.5 = 2.25\), \(2.25 \div 100 = 0.0225\) (adjusting place value) eg \(1.5 \times 1.5 = 2.25\), \(2.25 \times 1.5\) (cubing not squaring) | M1A0 M0A0 |
| \(1.5 \times 1.5 = 3\) | M1A0 |
| \(2.25^2\) \(225^2\) | M1A0 M0A0 |
