Using square root table, find the square roots of the following:
4955
Given:
Given number is 4955.
To do:
We have to find the square root of the given number using square root table.
Solution:
From the square root table, we find that,
Square root of 4955 is $\sqrt{4955}= \sqrt{10\times10\times49.55}$
$=10\times\sqrt{49.55}$
$\sqrt{49.55}$ lies between $\sqrt{49}$ and $\sqrt{50}$ i.e., 7 and 7.071
Difference between 49 and 50 $=1$
Difference between 7 and 7.071 $=0.071$
For the difference of 1, the difference in the values of the square roots is $0.071$.
This implies,
For the difference of 0.55, the difference in the values of the square roots $=0.55\times0.0701$
$=0.03905$
Therefore,
$10\times\sqrt{49.55}=10\times7.039$
$=70.39$
Therefore, the square root of 4955 is 70.39.
