![1.42=(1.42)/(100) * 100=(142)/(100)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/5vws9lbatyamexlqdv1lmeoix0hkoj93ua.png)
Now calculating the square root of
![(142)/(100)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/y1sk0rxhusfqlxgys0sdbemvzourddgbkt.png)
![√(1.42)=\sqrt{(142)/(100)}=(1)/(10) √(142)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/m17ggdy3ogb4sndug2advua2oia1o6674b.png)
On calculating square root of 142 using long division method, we get 11.916
So we get,
![√(1.42)=(1)/(10) * 11.916=1.1916](https://img.qammunity.org/2020/formulas/mathematics/middle-school/4pm9vjwi4wv0otka3pdnw2ccg9apmod9g7.png)
Hence square root of 1.42 = 1.1916.
