For an experimental expression \(y = \dfrac{32.2 \times 1125} {27.4},\) where all the digits are significant. Then to report the value of \(y\) we should write
1. \(y = 1330\)
2. \(y = 1326.19\)
3. \(y = 1326.186\)
4. \(y = 1326.2\)
1. \(y = 1330\)
2. \(y = 1326.19\)
3. \(y = 1326.186\)
4. \(y = 1326.2\)
