Question

2.5 sq root upto 3 decimal no.

Answer 1

Answer:We can solve this by either of the following methods:

1) by short cut method,

eg: If we want to calculate √(xyz.abc),

then we will have √(xyz.abc)=√(xyzabc)/√(1000)

∴ √2.5= √25/√10

on simplification we’ll get  

√2.5=5/3.162

Further simplification will give  

√2.5=1.581

2)By Long Division Method:

We all are families with this method since our school time,

we have two make the pairs of two digits,

∴ 2.5=02.50

And now we’ll apply that long division method
