Question

Finding the square root of $49$ using Successive subtraction

Answer 1

Find the square root using successive subtraction

Given number, $49$

So,

$$\begin{gathered} 49-1=48 \\ 48-3=45 \\ 45-5=40 \\ 40-7=33 \\ 33-9=24 \\ 24-11=13 \\ 13-13=0 \end{gathered}$$

The result $0$ obtained in the $7^{th}$ step.

Therefore the square root of $49$ is $7$.

Hence the the square root of $49$ is $7$.
