Question

Find the square root of 900.

• A. 30
• B. 40
• C. 24
• D. 34

Answer 1

The correct option is A

30

First of all we will make a set of two digits for 900, and we add 0 before 9 so as to make a set of two digits. Now, we proceed with the long division.

$\begin{array}{cc}& 30\\ 3& \overline{09}\overline{00}\\ & -9\\ 30& 000\\ & -000\\ & 0\end{array}$

Hence, the square root of 900 is 30.
