0.8
To find : The square root of 0.8 up to two places of decimal.
Solution :
Let x=\sqrt{0.8}x=
0.8
Squaring both side,
x^2=0.8x
2
=0.8
x^2=\frac{8}{10}x
2
=
10
8
Multiply and divide by 10,
x^2=\frac{80}{100}x
2
=
100
80
x^2=\frac{(4\sqrt5)^2}{(10)^2}x
2
=
(10)
2
(4
5
)

Now, Taking root both side,
x=\frac{4\sqrt5}{10}x=
10
4
5
x=\frac{4\times 2.23}{10}x=
10
4×2.23
x=\frac{8.92}{10}x=
10
8.92
x=0.892x=0.892
Up to two decimal places \sqrt{0.8}=0.89
0.8
=0.89
